Angelina Jolie really, really doesn't deserve an oscar for The Changeling. The movie was very well made, but she wasn't very good. It didn't help that they made her look distractingly like Betty Boop, so much that even in the scenes where she was supposedly in a mental institution for a few weeks, she had lots of eye make-up on (does she have eyeliner tattooed on? it appears so).
Even besides, she had an iciness that felt off. (It could be just her intense fame and the way that she markets herself so much as the ultimate mother in a way that doesn't remind me of moms.) All this stuff distracts when its a characters that she is playing.
Malkovich and Amy Ryan were fantastic in the movie though. If either one of them were nominated, it'd be justified (but neither will happen).
