A Clockwork Orange - I've gone back and forth and back and back and forth and back on these, and it comes down to the one I've loved the longest and the one that has "I Wanna Marry A Lighthouse Keeper" in it. I'll be delighted if The Godfather wins though.
It's interesting that in the semi-final rounds we'll have 2 truly great "art" films (yes, I consider The Godfather an art film) and 2 truly great popcorn films. That's as it should be. Once I realized that, I didn't feel so guilty voting against Red.
