Surprisingly decent
I only watched this because I was a huge fan of the game show as a kid, and didn't expect much. They actually pulled off a pretty good movie by being faithful to the game show, even though it was an entirely different format. They incorporated the rooms of the temple and animals from the original, and had great fun with kids struggling with the seemingly easy silver monkey and the trip to Space Camp as a prize.
I'd still like to see a special revival edition of the game show, but this did a good job of feeding my nostalgia needs.
