I played the demo though yesterday too (coop with a friend). The controls are not as sharp as they used to be in the NES version, and the new graphics are not as clear as the old ones. Sometimes it's hard to see who is who (in coop) and what direction you are facing. Otherwise the graphics are nice and the game is pretty good. However the demo started slightly to repeat itself at the end, so the full game might suffer a lot of this problem. According to Metacritic: IGN gave it 59, Eurogamer 70, GameSpy 50, GameTrailers 61 and TeamXBox 88. Turtles metascore is currently 66. I expected a bit better I have to admit.
