The basic notion of the film (two kids have lots of scary adventures with Robin Williams) must have sounded good on paper. But the technicians have filled the screen with special effects, both conventional and animated, in such a way that the movie is now about as appropriate for smaller children as, say, "Jaws." It's not bad enough that the film's young heroes have to endure an unremitting series of terrifying dangers; at one point, little Peter gets converted into a monkey that looks like a Wolf Man, and goes through the film like a miniature Lon Chaney, with a hairy snout and wicked jaws. This image alone is likely to be disturbing to small children. To me, it looked like gratuitous cruelty on the part of the filmmakers toward the harmless young character.
