one thing i dislike about dive be the testosterone fill self label expert diver that you will encounter on just about every organised dive you will ever do never mind the shark . the truth be that people with head swell by the experience ( which actually a senior age lady can do ) be the big threat to your dive safetyi just read a review by a dive expert that think this film be scary and realistic just like real night dive . apparently this person have dive on his own in open water and like the submariner and and therefore can tell you exactly what it must be like to be strand guy like this will tell you they be ex navy seal and then be so rubbish at dive that they will kick coral to smithereens ( true story ) personally i be not sure why even a semi factual attempt be make at this story . why not use it instead a the basis for a more extensive plot . nothing be know about what happen to the two people involve and it most likely they lose their life in a thoroughly un hollywood way and from exposure or drowning . the only surety be that the dive organiser and crew be totally incompetent the way the woman glide into the water at the very end of the movie and with shark visually feed on fish close by to her and be extremely glamorised and unrealistic a be the whole emphasis on shark a the lurking horror . the part where the dive camera be cut out of the shark at the end be wholly disrespectful and lack in taste and really quite ridiculous if you want realism you may as well watch deep blue sea .
