It sounds and looks like an old japanese movie that has been modernized with mediocre teenager chicks and dudes in an attempt to impress us with crappy animations of giant fish... by the looks of it, its two giant fish that have nothing better to do but destroy each other and everyone else... oooh!:headbang::banghead:
The shark biting the plane is 100% accurate. Im pretty sure thats actually what happened to that french airliner.
In all seriousness that movie looks completely retarded and thats coming from a true "shark nut." Jaws, Deep Blue Sea, etc etc etc are all movies I love, and I wanted to be a marine biologist for the longest time.
