the plot of this movie revolve around this submarine builder who a real bastard and he want to launch his new sub that can travel thousand of foot deep . unfortunately and he can not . oh yeah and and he haunt by the memory of his mom and dad get eat by a megalodon when he be a child . the guy meet some scientist whos pretty hot and and they and this crew of about a hundred people set out on the main character submarine to kill the same megalodon that kill his parent . now and the shark in this movie be a really fake look cgi shark . basically this be sorta like shark attack 3 and except more depressing . if you do not get what i mean and listen . the film open credit show home movie of the main character when he be a child with his parent before they get kill and and there really sad and depressing piano music playing in the background . you would expect to see a shark or something and and you do . a brief shadow of the cgi shark float around every few second but that just it . also and i do not remember one happy facial expression at all throughout the film entire runtime and a majority of the film take place in the dark depth of the abyss and where the story get even more dull and and all the character ( the shark too ) die in the end . i be think sabato would manage to kill the shark and manage to save himself and the girl and but no and they all die and and the film end with the shark and all blow up and and the submarine ( with sabato crush and burn body in it ) sink into the abyss . if youre a happy person and you do not enjoy be depress and then avoid this movie . if youre the opposite and then congratulation and you find your movie .
