Space, Time Travel, Robots, & Aliens!
Easily my favorite genre no matter anyway I look at it. I love the endless possibilities and ideas that so many brilliant creators can infuse in not only these films here, but in the idea of the genre as a whole. Multiple all-time classics and favorites listed!
As with every other genre list, the further down the list you go, the looser that the exact ranking starts to get. You can check my other genre lists here.
