When you said the movie was intended for younger children, I lost all respect for your review Jinny. I'm sorry to say that, but as an animation major that really upset me. WALL-E was a movie created for all ages. In fact, if you wanna get technical, younger audiences have trouble understanding it often. Animation is a medium, not an age bracket. Thank you.
Anyways, I played the PS2 version and had a lot of fun, though it took me only half a day to beat, and the unlockables weren't exciting enough to make me wanna shoot for them and extend me game time. A great game for fans, but renting it first may be a good idea. Non fans, as usual when it comes to licensed games, will probably find more fun in other platformers.
