Just be prepared for it, it’s definitely not a lazy Sunday morning film.
Others that would be worth a watch (if you haven’t already):
Requiem for a Dream
World’s Greatest Dad (bit of a wild card)
City of God
Babel
Biutiful
21 Grams
Also I’d really recommend End of Watch to anyone who liked Gran Torino. They’re quite different, but when I think of solid, entertaining American films that avoid getting too Hollywood and have a good mixture of scenes, they’re both somewhere near the top of my list.
It is surely possible to provide a film that entertains as well as seriously tackles issues of the day? Gran Torino does not do this!
Zombieland, Hot Fuzz, Scott Pilgrim vs the World. All fantastic films. Don’t think they really tackle too many issues. Sometimes it’s nice for a film to do that, but sometimes it’s nice when it doesn’t bother.
