there be only one word to say about this movie and that be bore . the plot represent a marine biologist head for port amanzi in africa after his friend and mark desantis and be supposedly a victim of a fatal shark attack . desantis have be conduct research on a series of shark attack in the area prior to his death and now his friend and along with desantis sister and take up the research and find that the shark may not be the only threat in port amanzi . 3 thing you should never do . 1 ) buy this movie . 2 ) watch this movie . 3 ) don not watch it again just to review it . the bad think about this movie be that the shark be real underwater and every time come above sea level it be fake and i do not even get me start on the fake blood . there be one good thing i can say about this movie be the act from small part of cast be okay .
