It's got a very faint Walking Dead vibe to it: a band of survivors avoiding monsters (human and otherwise) while trying to make their way to a better place. Despite the $17m budget, it feels very made-for-TV.
Cool: George Peppard! Giant scorpions, flesh eating roaches, and what has to be one the greatest vehicles in film: the Landmaster
Lame: Apparently 20th Century Fox went back and re-edited this after the unexpected success of another little movie called Star Wars. And that's too bad because I'm guessing they cut the parts that would have given this some kind of meaningful story.
The first film from the House of Corman to ride on Conan's loincloth tails, it's also the film debut of Lana Clarkson from the Barbarian Queen flicks. There's a barbarian, an evil wizard, some ridiculous creature makeups, and Barbi Benton. If that doesn't sell you, you should probably not see it.
