From the Contributor:

As a fan of the movie this game was an easy purchase at $20 just to see how it compared to the stunning visuals in the theater. It was a pleasant surprise to see that great care had been taken in making a very nice environment that captures the feel of Radiator Springs. Gameplay is very light, racing isn't difficult though some of the minigames suffer from bad camera angles.
