How bad is it? Messy "Road Warrior" clone with hit-and-miss effects.
Should you see it? Sure. Everyone should see one Charles Band film and this is a prime example.
This has a loyal cult following, as does every early film directed by Charles Band. There are roles for Tim Thomerson, Richard Moll (as a cyclops - makeup covers one eye), Kelly Preston and Michael Preston (who plays Jared-Syn and apparently is no relation to Kelly). Taking some ideas from "Star Wars," this is largely "Road Warrior" type car chases in the desert near Bryce Canyon, with some entertaining 3-D effects. There's a lot of padding, with characters just wandering around. The whole plot consists of trying to take down a bad guy who's collecting people's souls in a crystal. In the end, the evil Jared-Syn just goes away to leave room for a never-made sequel, so even the title is wrong.
