It’s been more than 30 years since Joe Dante made Piranha for producer Roger Corman. In his commentary on the new DVD release for the original, Dante says Corman kept demanding “more blood” when he watched the dailies. If Corman should take the time to visit a theater, put on the goofy glasses and behold the crimson gushers in the all new Piranha 3-D, I think it would bring tears of joy to his eyes. Spring break kids going for a swim in fictitious Lake Victoria in Arizona become fish food when prehistoric piranhas are released from their watery prison after an earthquake. While the film has some dopey passages, it does have the grisly distinction of being the goriest horror blast in many a year and, for this, I have to give it praise.
