Lots of times when a game pushes really hard for realistic graphics i feel it indeed does look realistic but also stale and boring.
To me its like plenty of things in cartoons/comics/animations looking cool in their natural setting but in real life it would look boring or stupid or even funny.
Im not against good graphics but i find life like graphics boring and makes the game less unique with no style. I like mario games, for example, but if they made the graphics life-like and realistic then it would look really stupid to me. (A grown man stomping a turtle to death?)
