Fantastic movie, with excellent acting

I studied this film for English this year. Frankly this is probably the best thing to come out of my english class. So in a nutshell, it's basically about a young teenage girl named Melinda Sordino who becomes ostracised due to a psychologically traumatic event leading to her social alienation and detachment from family and friends.

I have to say, excellent acting from all ESPECIALLY Kristen Stewart. She was amazing in this film, with her strong and powerful facial expression; her character really doesn't have many lines. Everything was really good; the music, camera shots ,etc
