I kind of predicted most people wouldn't take to the grainy, darkened IQ of CV. I still think it looks great and is a major improvement over the original.
I really don't think there is any problem with the controls, visuals or animations at all (except keeping the climb stairs button, that's bunk), but that's all everyone seems to focus on.
If there is anything the game deserves a lot of criticism for it's the confusing level design, brick wall moments where you have no choice but to restart, simple mistakes that can deprive you of important items at the very end of the game, and parts where you absolutely cannot avoid taking hits or dying. Some pretty poor game design all around.
The game was contentious when it came out and it's still contentious today. Anachronism has nothing to do with it.
