No doubt that most people that rent/buy/ watch this film will only do so because "It's by the guy that did Kids." Well, if you do so on that methodology, prepare for a shock, and certainly not a pleasant one.
Straight up, this film sucks. It's appalling. It's awful. Have you got the point yet? No? This film is pure, Grade A garbage, pure and simple.
It seems to be split somewhere between Clarke doing Kids-lite, and Stan Winston (how did they rope him in?) having a laugh with some ropey SFX that look like he was trying to pay off his credit card bill after buying every dinosaur from the Jurassic Park lot. The plot is, well, apocalyptic, and a bunch of teens leave their caves for the big city, and partake in some sex, drugs, and rock n' roll with some kids in the big city, but can't handle it in a very extreme way, which is Stan's cue for some SFX that wouldn't look out of place in any straight to video, bottom shelf, no-budget, less brains slasher flick (so good, they show one sequence twice - dear God). AND THAT'S IT. I have just saved you a couple of hours to do something else, be grateful, go and watch Donnie Darko; same run time, infinatly better.
Kids was good, Bully was good, Teenage Caveman is...an accident. Check the dictionary under "Film-maker's Folly", and the video cover will be there. From top to bottom, this is tripe. Watch if you are a sado-masochist, or more likely into straight to video, bottom shelf, no-budget, less brains slasher flicks, in which case you are beyond redemption anyway.
