I made the mistake of thinking this was the OTHER 70's movie by the same name, which is a delightful, fake-bloody romp where stupid people get eaten. This is about motorcycles, the view FROM motorcycles, and a psycho. There is only one tiny scene with Piranhas, and also there is a s**ual assault in this movie. Oh, and the sound is so bad I had to sit right in front of my TV, holding perfectly still. DO NOT BUY IT.
