My 25 all-time favorite science fiction movies (at the moment)

I was listening to an episode of "On Point" yesterday, and the topic was "greatest science fiction movies of all time." After listening to the podcast, which was a lot of fun, I said - "I accept your challenge!" I thought the world would benefit from knowing my all-time favorite science fiction movies.

I am very deliberately not calling this list "greatest movies" because these lists are inherently subjective and I'm just listing my own personal favorites. A few notes:

• I am keeping out movies based on comic books. While most of these would qualify as science fiction, I see them as their own category (and a list for me to work on for another day).
• I am singling out individual movies, not just series (which makes it more challenging in a good way) - so I will not just say "The Star Wars movies"
• These are my own personal favorites. There are many movies out there that are regarded as "great" that I haven't seen, or was not so impressed by; this list is only meant to cover my personal preferences.
• I can't just do top 10 because it ignores too many movies.
• If a movie falls into another genre but is also clearly science fiction, I am including it.
• It has been so long since I last saw Blade Runner, I suspect that once I re-watch it, my list will change
• If given another day, or two days or a week, I could probably monkey around with the order of the movies on the list (other than the top 5), so other than those, the order only reflects what I felt at the moment I hit "Publish Post".
• I have not included animated films. If I did, Wall-E would probably make the list somewhere.
• I have a suspicion I'm really going to enjoy District 9, but haven't seen it yet
• About Star Wars Episodes I and II, each of those movies has a lot that I enjoy, (for example, the light saber duel at the end of Episode I is my favorite in the entire series of movies) and it is hard to separate out all of the affection I have for them as Star Wars movies, but I felt that overall, they were not good enough to make the list.
• Avatar - one of the most visually stunning things I ever seen. Doesn't make the list. At least not today. I'm not sure how much I actually liked the movie, apart from the 3-D visual spectacle of it.

With that in mind, my list is as follows:

1. The Empire Strikes Back
2. Star Wars
3. The Matrix
4. Back to the Future
5. Terminator 2
6. Return of the Jedi
7. Dune
8. Star Trek: First Contact
9. Minority Report
10. Eternal Sunshine of the Spotless Mind
11. Children of Men
12. Star Trek (2009)
13. Galaxy Quest
14. Star Wars: Revenge of the Sith
15. Star Trek IV: The Voyage Home
16. Twelve Monkeys
17. Gattaca
18. Star Trek II: The Wrath of Khan
19. E.T.
20. Donnie Darko
21. Starship Troopers
22. THX 1138
23. Inception
24. Brazil
25. Robocop
