Query: A great slice of cheesy heaven

Okay, this film WILL NOT appeal to everyone. The acting is horrid, the SFX are nothing special and the basic plot will cause the head of any viewer looking for some trace of common sense to explode.But, if you're in the right mood, this film is a treasure trove of laughs and "What the hell" moments. Piranha munching on helicopters, leaping down a river like a school of salmon, and even hurling themselves into seafront highrises. And don't even get started about the hero kicking the nasty fishes as he's attacked on the beach! I still laugh at that moment.It's a crappy movie, and I won't try to convince you otherwise. But it will likely appeal to fans of low grade cinema. If you enjoy the old Roger Corman stuff (like Attack of the Giant Leeches), you might give this one a try. Anyone looking for something more serious, I suggest you stay far away.
