I don't understand the nay-sayers of this film. Yes it had unbelievably realistic looking action scenes, but it also had a pretty decent story to back it up. it totally reminds me what it would be like and what humans would act like in a real situation. of course you must formulate your own opinion, but it's certainly the best movie I'VE seen this year! After what seemed like a season of disappointing movies, finally something good.
