Charlize--awesome and my pick.
Ditherspoon--deserved it for Legally Blonde, did not like Walk the Line
Mirren-It was ok, but not my favorite
Cotillard-hate subtitles, haven't seen it.
Winslut-pretty good, the part where she adjusts his penis for anal penetration is a nice touch, but not my favorite
Buttocks-deserved it for Miss Congeniality, Blind Side was garbage
Portman-haven't gotten around to seeing it yet, but it's in my Netflix queue with I Dismember Mama and Season 2 of the Big C
Streep-it was very good, but not my favorite
Lawrence-haven't seen it, but likely will at some point.
