What the heck? Why has Treat Williams been making such lousy movies? And George Miller? Is this the same George Miller who made the Mad Max movies? I can't believe that the man who gave us "The Road Warrior" made this embarrassing movie, too. It seems to be true, though....
This is a harmless enough movie, but prone to sentimentality, and very predictable plot contrivances. The villains are a breed of bipedal reptiles with huge claws and frightening teeth who, when they jump our heroes, merely jump them and try to wrestle them to the ground...they don't bite. They don't slash. They wrestle. At one point, Treat Williams appears to kick off the "head" of one of these beasts...or to knock off the headpiece of the costume. (You don't see more than a few of these creatures at once, although we are to believe there is a large society of them...clearly, the producer did not have an adequate costume budget!)
I like camp, and there is a certain campy element to this movie--intentional, I hope. The subterranean tribe of humans who take our heroes, for instance, in are made up of brutish, hairy, grunting men, and utter babes in two-piece bikinis. They have wonderful midriffs. And they are not the least bit sexually bashful. What a break for our travellers! If this is deliberate camp, it's played too straight really to work.
I dunno...rent it for the kids, I guess. But don't incur any late fees with this one. You'll be sorry.
