I've watched most of those movies and I'm glad most them won.
For those of you who don't know, Slumdog Millionaire's about an Indian teenager raised from the slums who plays in the Indian version of "Who Wants To Be a Millionaire?" and wins the million dollars. I watched it last week. It's really good.
The Dark Knight's about, well, Batman (duh) who defeats the new threat, the Joker, and Two-Face. It's the sequel to Batman Begins and it's also really really good.
