In The scene when the shark is in the pond and eats that guy in the red boat, he get knocked off and the shark swims under him and bites his leg and holds on(you can see this because the man attempts to get on his boat then is dragged back into the water)and the shark continues swimming under his boat, then in the next scene of the man, the shark is up at his waistline. So that means the shark would have to swam backward or let him go and swim in a circle a bite him again? And then you see his leg hit the bottom of the pond, but the shark had is legs in his mouth? how can this be???
