Chloe Moretz is a little too pretty for the role. Why do all the girls hate her, because all the guys want to frick her?
I read some behind the scenes stuff that said she played her part differently than Spacek. Moretz is pretty, but the years of abuse is supposed to make her feel "ugly" inside. Which, supposedly is how it is supposed to come across on screen. Basically i guess like a socially awkward, semi pretty girl. With a very low self esteem. Supposedly Moore as the mother does a really good job from what i read also.
