Solid story, nice set of unconventional characters, and outstanding visual effects--I actually got vertigo a few times--all add up to a well spent 90 minutes. Take the kids or not, it works either way.
Incidentally, that's Florence Stanley as the unflappable old woman with many of the best lines. If you're wondering why you know her voice, there's a good chance it's because you're a Barney Miller fan (she was Fish's wife).
