Wait a second man, there are two Dawn of the Dead's, you know that right? The first one which was Romero's and the second one which was a remake by Zack Synder, both are completly different. Second this ain't some sort of video game this is real life. If there were really an outbreak of zeds you would want them slow and stupid as possible, your survival depends on it. Your acting as this were some video game and your life doesn't matter.
