Jumanji is based on a creepy-looking picture book by Chris Van Allsburg that’s also called Jumanji.
It’s an expensive, high-tech movie, but the plot (perhaps unsurprisingly) ends where it starts (in the past), and all the accumulated damage is reversed.
I have trouble believing the giant crocodile was ever convincing, and the effects team admits to basing the monkeys on no monkey in particular, but the plants were pretty cool, and the stampede was amazing.
The running gag with the car was hilarious, and it was fun to see Robin Williams act the part of the man-child from the jungle. He’s awfully good at being silly and yet serious, as he is in Hook (which I liked better).
