I think A Clockwork Orange is a great movie, not my favorite, but still great.
American Pie kicks ass! I could watch the internet scene 100 times and choke with laughter each time!
@ Witchfinder: I'm Italian, so obviously I love Dario Argento! I actually forgot to put his movies in my favorites. I've seen all his movies, especially the earlier ones. By the way, Goblin play the soundtracks on the earlier movies, like Suspiria, Inferno and Profondo Rosso, but not on Phenomena. The Phenomena soundtrack features Iron Maiden ("Flash of the Blade") and Motorhead ("Killed by Death"). Need I add more?
