Review from a dad and almost 6 year old son
It was loosely based on the original Jimmy Neutron Boy Genius Movie. You had an idea of where you were at in the movie, but did not actually perform any of the steps that were seen in the movie.
There was at least one voice that was not the same as the cartoon. That was one of the things about this game that bothered me, but did not seem to phase my almost 6 year old at all. He really enjoyed playing this game.
In short, if you can find the game for under $20 and it is for someone in the 5 to 8 age group, it will probably be worth the money.
