I hope that was a joke, seriously. It's a shame that Rockstar hasn't tweaked it properly else it would have been a serious competition for other sandbox games as well. If you look at the previous GTA series they all have a cartoony look to them. This engine uses a great amount of detail on both texture & character modelling. Rendering each component in this game is no joke. Look at the Vehicle reflections which are extremely polished compared to both SA & Vice City. The city itself is so vivid looking that you can't help but just gaze it at. Every nook & corner of the city is different. Not one alley looks similar to the other. That's the amount of detail this game has.
If you have played the game & observed the explosion effects then it has an extremely realistic feel. Even the cut-scenes are rendered on the fly & are not pre-rendered. So If I have dressed up Niko in a suit & run into a cut-scene he will still be wearing it, unlike some games where it changes due to the pre-rendered nature. The amount of draw & detail distance this game has you won't even bother looking back at GTA: SA & VC after that.
The only reason why people feel that it's crap is because it's not properly optimised & runs into graphical glitches. But in reality to render so much detail in a sandbox game isn't a walk in the park. Comparing it graphically to the earlier GTA games is a capital sin.
