When I see a movie, there are some things I'll tolerate - Tarzan, a superhuman outswimming an alligator ok. An 80 pound Olympic swimmer, who gets grabbed by these giant, prehistoric monsters no less than FOUR times? No, sorry. A stupid story and lame sfx equal a bad movie. This goes from dumb to dumber to dumbest on a matter of minutes. While it's true that a strong human can hold an alligator's mouth shut, once it closes on prey, it drags them to the bottom where, once drowned, they are eaten. Pops splitting ones head open with a shovel was almost believable. This was stupid on a new level - even dumber than the directors lame remake of piranha! At least, surprisingly, the dog lived!
