I don't think this movie will do great, the concept is very predictable. When I saw the trailer I was like "Erm, we already have The Hunger Games, no thanks".
I knew they wouldn't get a high rating. The critics stay pressed. We all knew this movie wouldn't win an academy award, but I feel it's sorta unfair for anyone to call it a bad movie who hasn't read the book, and I'm sure the critics haven't flipped a page.
