This is a great thread.
I don't consider myself a movie buff, but when I see a *deep* movie, I enjoyed it immensely. This thread has given me quite a few to check out. Thanks.
There are no Anime movies mentioned so far, so I'll just toss a couple that I think are up there in terms of plot and aesthetics:
- Tokyo Godfather (very funny and very touching plot)
- Patlabor: The Movie (I and II), yes, this is about robot and mecha, but the plot twists and the philosophical musing in it are definitely not aimed for youngsters. And the music, ambient, and cinematics are superb.
Back to real-people films:
- Central Station - set in Brazil, beautiful plot, story, and even some stunning shots
- Red Cliff - adaptation of one of the famous battles in the Three Kingdom saga. Grand battles, beautiful movie, I think it's better than Hero (Jet Lee).
- In Custody (by Ismail Merchant) - this movie set in Northern Indian culture is raw, deep, and very touching.
- The Legend of 1900 - strange film, but one of my favorites. Excellent music.
As for the classics, The Last Emperor, Dr. Zhivago (don't quite like the plot, but that's a beautiful movie).
