ahh yes i forgot about that. good point. But then why use the knife at all?

Not being able to move is very restrictive. It was one of the main things that stuck out to me having not played the series in a long time. The game feels dated. Zombies run up to you and stop so you can shoot them or stand there and swing your knife as you STAND STILL. You can make the excuse for the gun but not being able to swing the knife while moving just makes the game feel frustrating. I will rent it and play through but I don't have to like it. They should never restrict control to make up for crappy zombie AI.
