I'm confused as to why viewers think he is trying to make these fish out to be more vicious than they really are.. I love this show and have watched all the episodes back to back. The piranha scene was to show how exaggerated their aggression is. He was making a point that you could go swimming with piranha without them tearing up your flesh. In the snake-head episode, he never once stated that these fish come out of the water and eat your children. In fact, he was trying to disprove this myth. He said that despite what Hollywood has said, Snake-heads are certainly not the man eating fish people thought. The whole premise of the show is this: He hears about some fish related deaths, he reads or talks to people about local myths and legends about the fish, he investigates, he catches the fish, and then the show almost always ends with him saying either "Although a monster of a size, this fish is really just a gentle giant" or "Although a brute predator in the wild, only in extreme circumstances would this fish cause harm to a human."
