10 Most Rewatchable Sci-Fi Series of the 21st Century

I’ve noticed that even though we’re getting so many well-made shows these days, something special is needed to make me want to watch something again and again. A lot of newer sci-fi can be really challenging, with complicated storylines or heavy themes that take a lot of effort to follow. But the shows I really love, the ones I keep going back to, just pull you in. Some of them are comforting – like hanging out with old friends because you know the characters and the way the show works. Others are packed with little details and hints that you only pick up on after multiple viewings, making each re-watch feel completely new and exciting.
