The one negative aspect of the film may have been a fluke of the press screening: The sound was grating and murky. The painful volume in the theater was no doubt part of the problem. But even compensating for that, it sounded as though the sound mix was excessively shrill and muddy. In one number where bits of several songs are reprised all at once -- in the manner of the prerumble sequence in West Side Story -- the parts fused into an unintelligible whole, an ugly bouillabaisse of noise. I'm sure it would have been much funnier otherwise.
Still, for South Park fans and for those without priggish sensitivity to the way their children really talk behind their backs, Bigger, Longer & Uncut delivers: It's never less than funny, and at its best, it's truly hysterical.
