I know I'm going to ruin it for everyone...But I was really put off during the gunfights by two things: 1. None of their guns kicked at all in the prison clearing scene. They didn't move, they weren't even shooting blanks, they just had some CG muzzle flashes and that was it. Picking off zombies, in the head, from guard towers? Come on man. Even if they had some unlimited stash of ammo with which to practice, and used all their time to do so..a pistol and a human eye/hand is just not that reliable. A pro couldn't consistently make those shots.
