Wow, all the previous lists were full of some pretty good movies in every ones list. So far all the mentions of good 00's films seem pretty flacid to me. Has it really been that awful of a decade for film (heh, if you can even accurately call them films anymore)?
I guess I will take a go at a list, my top ten, not long thought out, and in no particular order (ranking them takes WAY too much brain power, and doubtless my order would change from day to day).
1. Serenity
2. Primer
3. Spider-Man 2 (really liked part one as well, but I don't want to put both in the top ten, and I felt two was slightly superior to one).
4. Fellowship of the Ring (same as the above, next two installments were also top quality, but the first one ranks higher in my book).
5. Children of Men
6. Eternal Sunshine of the Spotless Mind (really, really pains me to put a movie starring Jim Carrey on this list, but I think this film deserves it).
7. Pan's Labyrinth
8. Gladiator
9. Amelie (Yeah, I actually do like Jean-Pierre Jeunet... when he isn't making Alien sequels anyway).
10. Gran Torrino
Honorable mentions,
Kingdom of Heaven (Director's cut only! Theatrical was pretty awful).
Pirates of the Caribbean (come on, it was the best action/adventure movie it his the big screen in years. It's sequels totally drove it into the ground with unforgivable awfulness).
Shrek (I am not into kids movies at all. Never had any interest in seeing this when it was first released, then I caught it on TV one day and was quite impressed. Good balance (or perhaps unbalance) of things that appeal to kids, and humor intended to keep the adults that accompany them amused. Not to mention it was actually fairly profound for what it was: a shallow kid's flick full of fart jokes).
300 (for what it was, this film was nearly flawless! A lot of the hate came from people who came in expecting/wanting to see a more historically accurate portrayal of these events, or the fans of films like Troy and Alexander, and where hoping for an action drama more along these lines. No such luck, instead they got a cut-off-your-head-and-piss-down-your-neck-cavity-high-paced-action-flick filled with non-stop CG flow of blood, with several memorable quotes thrown in for good measure... now that I think about it more, this film should probably be on my actual list and not in the honorable mention appendix... oh well).
All I can think of off the top of my head.
