Here we go again...
Zombies can not retain ANY information of their former lives, because they're brains are COMPLETELY ROTTED OUT, becoming a Zombie does NOT make you a super powerful human being, and Zombies lack the ability to USE objects as a WEAPON.
The violence and gore is like something Quentin Tarentino would do, but less impressive. Oh GOD, and the voice acting. It was poop...no, it was like if poop took a poop, and that poop took another poop that poops out more poop. It's an infinite loop of poop. A poop loop.
