Jerry, just like Mermaids, they made it look real at the very beginning talking about the boat sinking/attack. They wanted it to look real all the way through. Unfortunately, when they started doing the interviews just like they did in Mermaids, I saw the huge similarities in the two and knew exactly what it was. A big flaw to me, if you are in South Africa for shark related stuff, you will talk to Chris Fallows. Period. I watched about the first hour, but didn’t finish it. I am interested to know if "Submarine" is, in fact, a real shark or not.
