Query: 5 stars Because of Robert Pattinson's Outstanding Performance

I gave this movie 5 stars because Robert Pattinson did such an AWESOME job as a paralyzed soldier. I could almost feel what he was going through. But I honestly did not really understand the film,especially the end. Why he did what he did. Not sure if he went insane or what. But I will have to watch it again and see if i understand it better and would like to read the book. Maybe it will give me more insight on it.
