I was just used to being able to hold down L or R and aim all around and you can't do that you gotta like move the c stick and and walk a certain direction just to aim somewhere and I found this quite annoying and impractical, plus walking around just seemed kind of herky jerky like the screen would bump up slightly then bump up down when you stop which doesn't make a whole lot of sense to me. The guns and character models seemed kinda cartoony which I don't like either. That's as good an explantion I can give as to why I don't like it. Pd really slows down on the villa level on co-op but besides that I never thought the framerate was a problem.
