Best sci-fi movie

If we're talking series, it's gotta be Stargate for me. Hands down.

But about movies, there's so many to pick from...

Blade Runner.
Guardians of the Galaxy 1 and 2.
Ghost in the Shell, was okay.
Black Out, is like a classical action movie. But in space.
All the new Star Trek movies.

... And more!
I'd love to hear what other people has to say as well. :D
