I just went through several top 40 to top 75 lists, not one of them mentioned go, which I liked a lot. And only one of about 6 lists mentioned Metropolitan.
I'm not saying go is the best film of all time, but it is a genuinely solid movie and half the films on these lists are dreck. Obviously, Metropolitan is almost as much a filmed play -- but it is excellent.
Any other oft-overlooked favorites? Or favorites that everyone likes?
