I don't get why this film is so popular. It's got a dull story line that dosen't make sense at all, i mean sharks don't just attack like that and it dosen't even explain why the shark went a bit nutty. Its too long and the lack of intresting story line is just about far to boring for watching. It's not a good movie tbh and by the end of the film it was just spinning on ridculous, think about it how could they swim back to sure with sharks like that in thier sea (they were in the deep aswell). I don't mind the plastic shark and the docutmentary images (i think) of real shark footage underwater. It's just it lacks in most important aspects to make a good film.
