Some other things:

Kate Winslet looked gorgeous. Thought it was funny they played Titanic music when she came out.

I thought Colin Farell gave by far the best presentation of all the groups of actors. His seemed natural and you could tell he and Jeremy Renner were really friends. I also liked Michael Sheen's presentation to Helen Mirren, Stanley Tucci's to Meryl Streep, and Oprah's to Gabourey Sidibe.

Based on the clips for Best Actor, Colin Firth looked really amazing.

Very happy for Sandra Bullock. I always thought she was underrated. To me, she is just so natural on screen and makes her performances look effortless. I always thought she deserved more attention for Crash, and I think her comedic skills are under-valued (as are most people's comedic skills). I also like that she won for something that no one originally thought was an Oscar-baity role.

I don't see Hurt Locker as an upset at all. It seemed like everyone wanted to bring the behemoth Avatar down.
