It was okay.
Was a bit boring to me actually. If you like those dark type movies check out :
Deadman Wonderland
It's about a middle school boy one day going to class and something devastating happens and he ends up getting convicted for something he didn't do.
He winds up going to prison where people have special powers they create out of their own blood. He starts to learn about it etc and let's just say a lot of people die. It's a dark movie.
