The controls are fine.
The point of the game is tension. If you could move and shoot, all tension is lost. Enemies can be both fast and slow. The whole point is kill them before they get in your face and shoot cum in your eyes.
With move and shoot, you could easily do this. By making the combat both offensive and defensive with a mix of item conservation, evasion, dodging, and context sensitive melee, you have controls and a gameplay system that strive for a totally different thing than Dead Space's aim.
The fact that people like you are completely unable to understand the intent of the controls is annoying. RE4/5's controls are fine and 1000x more satisfying than any move and shoot controls. Shooting a Ganado in the fucking face, running in, and suplexing that mother fucker is so satisfying. Got damn.
