Too often today, movies aspiring to recapture the manic energy and over-the-top schlock of 70s-80s exploitation cinema fall painfully short. Their ad campaigns promise gore and sex galore, but the overly slick productions featuring prepackaged stars from the CW which actually make it to theaters look more like the car commercials and music videos of today than the grindhouse bloodbaths of yesteryear. PIRANHA 3D, however, is a genuine throwback to an era fondly remembered but rarely done justice. Like the environmental horrors of the 70s and the slasher sagas of the early 80s, this no-holds-barred exercise in excess delivers 90 minutes of logic-free blood and boobs with aplomb. It's as unapologetically dumb as a movie can be, but it's more fun than the last ten horror remakes to hit multiplexes combined, and the fact that it refuses to ever try and be anything more than a mindless, topless gorefest makes it one of the most honest and forthright productions in recent memory. High art? No. Grand Guignol? Yes. Worth every penny of the admission price.
