10 Sci-Fi Movies You Need To Watch Twice To Understand

Science fiction stands out as a perennially captivating genre in contemporary storytelling due to its expansive subject matter and imaginative narrative style. Its appeal is underscored by the remarkable tales it has woven into cinematic lore, ranging from sweeping space sagas to thought-provoking indie films that delve into the potential ramifications of scientific theories. The genre’s adaptability and thought-provoking nature make science fiction a staple in today’s movies, with each compelling sci-fi film intended to spark debate or reflection on our future, present, and the evolution of human civilization and technology in diverse ways.

Science fiction is known for its intricate narratives, frequently incorporating surprises or unforeseen conclusions, which often necessitate multiple viewings to grasp fully. These films, when they drop a major revelation in the climax or reserve crucial context for the last scene, require a second viewing with fresh knowledge to comprehend completely. While this isn’t exclusive to science fiction, it seems that there are many sci-fi movies where rewatching is essential to make sense of them.

1) Interstellar (2014)

Christopher Nolan is often recognized not just for collaborating frequently with the same actors, but also for crafting thought-provoking science fiction films that leave audiences in awe. One of these movies is “Interstellar,” released in 2014, which revolves around a future Earth nearing extinction and an urgent expedition to locate a new celestial home. The narrative unfolds in one era and location initially, but later splits into two distinct timelines: one tracing the journey of the astronauts and the other focusing on those left behind on Earth.

In a significant manner, Albert Einstein’s theory of relativity impacts the narrative, causing a discrepancy in the timelines of Cooper and his daughter Murph’s concurrent tales in the movie Interstellar. The revelation in the third act, where Cooper leverages a time-space anomaly engineered by advanced beings to communicate with Murph across different periods of time and space, subtly yet effectively reshapes the entire film’s narrative. Watching the film for a second time offers viewers an opportunity to follow its storyline while simultaneously grasping the intricate science behind it, thereby enhancing their comprehension of its logical flow.

2) Looper (2012)

Numerous fascinating films explore the theme of time travel, and each presents a distinct perspective on this concept. The 2012 film “Looper” offers a fresh perspective, portraying time travel as a one-way trip that becomes illegal following its invention. It’s utilized by criminals for assassinations without detection. In this film, Joseph Gordon-Levitt’s character Joe is assigned his last task – to kill his future self (portrayed by Bruce Willis) – a mission known as closing the loop in his own timeline.

The act of Future Joe fleeing sparks off a chain of events that culminates tragically with both Young and Old Joe meeting their demise in a surprising climax. Recognizing that his future self aims to slay an innocent child to safeguard his destiny as a potent telekinetic, Young Joe elects to take his own life to shield the boy. This thought-provoking ending demands careful contemplation multiple times before its depth can be fully grasped on a broader scale.

3) 12 Monkeys (1995)

The film “12 Monkeys” often gets overlooked when discussing exceptional time travel narratives, yet it’s one of Bruce Willis’ standout science fiction performances. In this movie, Willis portrays James Cole, a future convict living in an Earth devastated by a lethal virus, forcing the remaining population to take shelter underground. Sent back to the mid-1990s on a mission to prevent the virus’s initial outbreak, Cole eventually discovers that he is trapped within a paradoxical time loop leading to his own demise and ultimately realizes that he cannot avert the disaster.

12 Monkeys subtly hints at its conclusion from the start, as Cole recalls seeing a man get killed at an airport when he was just a boy. Later, we learn that this man was none other than Cole himself, which significantly alters the film’s narrative. On subsequent watches, the movie appears completely different due to this revelation. Once you understand that Cole’s journey into the past was essentially predestined, you start noticing how his actions inadvertently contribute to the outbreak. Repeated viewings of 12 Monkeys make its story seem even more dismal as a result.

4) Inception (2010)

Christopher Nolan’s “Inception” is famously known for its intricate storyline weaving. The film follows Dom Cobb, a specialist in entering dreams, who is given the mission to plant an idea within the subconscious of a wealthy businessman instead of stealing one as usual. Alongside his team, Cobb ventures deep into the mind of this powerful tycoon, resulting in a reverse heist like no other. With dream sequences forming the setting, the movie presents thought-provoking visuals, and a narrative that becomes more intricate as it unfolds.

While Inception doesn’t typically end with a shocking twist like many other sci-fi films, its open-ended finale, paired with its intricate plotline, often leaves viewers pondering and seeking answers. To truly grasp the full implications of Cobb’s plan in planting an idea, one viewing is not enough. However, it’s only during a second watch that we discover the final scene reveals Cobb might still be dreaming, which can leave room for speculation about the movie’s true ending. During this rewatch, viewers search for subtle visual hints to understand the meaning of the closing shot, leading them to explore the storyline in more depth, just as Cobb and his team were compelled to do.

5) 2001: A Space Odyssey (1968)

2001: A Space Odyssey,” a legendary science fiction film, is often hailed as one of Stanley Kubrick’s masterpieces. It captivates viewers with its chilling portrayal of a sci-fi robot and compels them to revisit it due to its thought-provoking narrative. The movie chronicles a space voyage where astronauts face challenges from their computer system, as well as various episodes that initially appear unrelated.

The unconventional and somewhat experimental style of the film “2001: A Space Odyssey” has earned it a reputation as one of the most puzzling movies ever created. By the time its ending arrives, many viewers are left bewildered, although its stunning visuals and music make it worth re-watching. It’s questionable whether a second viewing truly clarifies Kubrick’s vision, but there’s no doubt that this film demands more thoughtful analysis than one viewing can offer.

6) Primer (2004)

As a passionate movie enthusiast, let me tell you, not every thought-provoking science fiction masterpiece has to break the bank. Take “Primer” from 2004 for instance – an indie film that’s as captivating as it is complex. It follows the journey of two ingenious scientists who stumble upon time travel, but soon find themselves entangled in a labyrinthine web of paradoxes and consequences.

Often overlooked amidst the glitz and glamour of big-budget productions, “Primer” is one of those hidden gems from the 2000s. Its intricate narrative demands multiple viewings to truly grasp its logical intricacies, making it a riveting watch for those who love delving deep into the science fiction genre.

A significant part of Primer‘s charm lies in the complexities of its narrative structure. The intricate time travel plot it presents forms a crucial aspect of the film, and with such depth, it becomes nearly impossible to completely comprehend in just one watch. Primer‘s exploration of time travel and the consequences of temporal displacement adds layers of complexity to the story, prompting viewers to reconsider their interpretations to decipher the film’s underlying messages about its characters and their actions.

7) Donnie Darko (2001)

Despite not typically being categorized as one of the most petrifying sci-fi films, the 2001 movie “Donnie Darko” carries an unsettling atmosphere. The plot revolves around Donnie, who miraculously avoids death while sleepwalking, and then encounters a mysterious figure in a bunny suit who warns him that the world will end in 28 days. The narrative that unfolds is enigmatic, and the interpretation of its conclusion has sparked intense discussions for quite some time.

At the conclusion of the film “Donnie Darko,” Donnie’s demise suggests that his actions throughout the story were unnecessary, yet he deliberately sacrificed himself to preserve Gretchen’s life. The abrupt disclosure at the end can leave viewers perplexed, frequently prompting them to rewatch the movie to decipher its deeper significance. Given its intricate themes of mental health issues and quantum theory, “Donnie Darko” is a film that may require multiple viewings to fully grasp its meaning.

8) Coherence (2013)

In simpler and more conversational terms, the 2013 film “Coherence” may not be the sci-fi movie everyone’s talking about when discussing the genre’s best works, but it certainly should be. The story revolves around eight adult friends gathering for a dinner party, complete with the usual interpersonal dramas that such gatherings often entail. However, as they celebrate, a comet passes overhead, causing some bizarre cosmic events that seem to significantly alter their reality, or at least their understanding of it.

One of the most puzzling science fiction films in recent times is Coherence, primarily due to its narrative revolving around the manipulation of reality. Figuring out the symbolism behind the movie’s depicted events isn’t easy, and a rewatch becomes almost essential for grasping its message. Upon closer observation during subsequent viewings, even the tiniest details become crucial in helping unravel the complex, mind-twisting plot it presents.

9) Arrival (2016)

In simpler terms, Director Denis Villeneuve’s debut into science fiction was a massive triumph. The 2016 film, titled Arrival, was well-received both by critics and audiences. Based on Ted Chiang’s short story “Story of Your Life,” the movie focuses on Louise Banks, a linguist tasked with understanding the complex pictographs used by alien arthropods that have appeared at multiple Earth locations. Throughout the film, we see glimpses into different phases of Banks’ life, and the ending flips the entire story on its head.

A key element of the science fiction film’s conclusion has Banks understanding that the alien language is read from both ends. This discovery implies that the aliens perceive time in a non-linear manner, suggesting that her supposed flashbacks are actually glimpses into her future. This twist compels viewers to reconsider the entire movie, presenting a fresh viewpoint and making Arrival an engaging and thought-provoking film experience.

10) Tenet (2020)

Christopher Nolan is known for creating thought-provoking films, and among them, none match the intricacy of his 2020 production titled “Tenet.” In this film, John David Washington portrays the protagonist, a character who joins a clandestine agency on a mission to discover where artifacts are originating from that seem to be moving backwards through time. The plot of Tenet delves into the investigation of a technology capable of repositioning time, which makes objects behave as if they’re moving in reverse.

I must confess, watching Tenet was an intellectually challenging yet incredibly rewarding experience for me. This film introduces you to a unique idea that feels alien at first, but as you delve deeper, it’s like piecing together a fascinating puzzle. The movie’s plot twists and turns in ways that require careful thought and a keen eye to follow.

The unraveling of the organization’s leader in Tenet is nothing short of ingenious, and while it may seem subtly apparent, it leaves you wanting to revisit the whole film again to truly appreciate its intricacies. The climactic revelation of the story’s key elements isn’t given away until the very end, making Tenet a movie that deserves multiple viewings if you want to fully grasp its captivating narrative.
