Wow--leave for a day and almost miss voting on a round!
1) The Empire Strikes Back. I'm just not an oldschool Star Trek Fan, and TESB is my favorite of all Star Wars movies.
2) Galaxy Quest. Loved it, and again, didn't much like old Star Trek.
3) Close Encounters. Truth be told, I don't much like either of them, but Contact committed two sins: first, it was too blatant in its emotional manipulation; and second, the last five minutes of it completely undo the power of its central theme (whether a skeptic must ever take a leap of faith).
4) Spiderman. The old Superman is very satisfying, but Spiderman is just wonderful.
5) Being John Malkovich. If I hadn't seen the first thirty seconds of Dark City, in which a character completely ruins the movie by explaining to you in advance what's going on in the mystery, it'd be a tougher choice.
6) Neither. Like everyone else, I haven't seen either of these,a nd I don't think I've even heard of Fallen. But I've been wanting to see Frailty, so if you need more votes on this pair, count this as a vote for Frailty (albeit a frail one).
7) Blade Runner. I really wanted to like Solaris, but I just couldn't; Blade Runner (the non-narrated version, anyway) is the best cyberpunk movie I've ever seen, and is one of my favorites.
8) Predator, by a hair. I didn't like Aliens as much as I expected to, given the hype about it, and I liked Predator more than I expected to, so this may just be more a matter of expectations.
Sorry to mess up some of your pairings--I'd been thinking of doing both Dark City and Being John Malkovich (in different matchups) myself, and had actually planned on doing The Matrix vs. Tron before I remembered Videodrome.
