I didnt really like any in 2012 but the better one for me that iv seen was The Gray i think just cos when he tells the guy hes going to die at the beginning and they all witness him pass away and when they feel they should take the time to make a prayer and the end when hes yelling at God for his help and then the sudden end when all the wolves leave but the leader, is like maybe he killed the leader or maybe he dies.
