Silly nonsense about a post-apocalyptic future where it doesn't rain and the kids are raised in a prison. There they play a game that's kind of a kids' version of Rollerball and wait to grow up and become guards or something for the corporation running the world. They find a glowing alien ball called Bohdai and uninteresting stuff happens. Laughable to the extreme, with ugly-looking '80s costumes and an odd fascination with rollerskating. It's unintentionally funny at times, and I totally give it points for that, but ultimately it's just embarrassing for all involved. See it for Jami Gertz, because you should see anything with Jami Gertz.
