I like Broken Lizard more than I like their movies. Beerfest might be my favorite, not Super Troopers.
Syndromes and A Century - I just didn't get what I was watching. And I'll be honest, it really bugs me when I don't get a movie. (See my review of Inland Empire.) But there was no mystery hooking me in. Nothing that made me WANT to figure it out, except for the fact that you all seem to get it and love it.
Also some more animation:
The Emperor's New Groove-- Not as funny as the Pixar stuff.
Hoodwinked-- I thought it was shoddy, poorly put together
Persepolis-- Everything I wanted from this, I finally got from Waltz With Bashir. This was okay, but I constantly felt like I was on the outside.
