If two heads are better than one, are three heads better than two?
So...the 3 Headed Shark is angered by ocean pollution, but it eats the sea garbage, which drives it insane and it starts attacking. This movie makes no fucking sense. It is also somehow a sequel to 2 Headed Shark Attack, but HOW??? There are none of the same characters and no relationship is implied between the 2 Headed and 3 Headed Sharks. I need continuity, dammit!
