My Top 10 Sci-Fi Movies

[Organic Machine]

My top ten in no particular order:

(intentionally left out Star Wars and Star Trek, I love them but find it too hard to choose between and not include several)
(2001 is one of those things where I feel like I should pick it and while I enjoyed it, I still don't know exactly how I feel about it)

Blade Runner (1982
Ghost in the Shell (1995)
The Matrix (1999)
Alien (1979)
Aliens (1986)
The Thing (1982)
Donnie Darko (2001)
Wall-e (2008)
Terminator 2 (1991)
Event Horizon (1997

Was Donnie Darko really sci-fi though?

I struggled with this actually, but I consider it to be. Maybe not in the traditional sense. It's got time travel.
If I had to replace it with something more traditional it would probably be replaced with Minority Report, Interstellar, or Prometheus.
