How about that Naomi Watts movie - Funny Games? It's received some really mixed reviews - some are calling it dark, grim and intense; others are calling it twisted, exploitative and manipulative. I like the actress and she generally does good work so I would watch it just for her.
Recently saw '4 Months, 3 Weeks and 2 Days'. It's a Romanian movie that won the Palme D'Or last year. Got rave reviews everywhere and I was expecting something truly epic and brilliant. I won't say it's bad but not as good as I expected. It doesn't really have an intro or an ending - just a lot of the middle, if that makes any sense. Just a really hectic & grim day (~12 hours) in the life of a young college girl helping her friend get an illegal abortion in mid-80s Romania. Give it a shot if you like artsy European movies.
