this movie be a hoot . bad stock footage and bad acting and bad story and just plain bad . lot of opportunity for a laugh . i do not think they mean it to be a comedy and however . i especially enjoy ( be highly amuse be a good term ) the growling shark . they appear to be great white in several shot and but sound like tiger ( g ) . the acting be rather wooden which contribute to the overall poor production . basically and an alien space accident result in a module be cast into the ocean . a few year later and a portable lab be position close to the module and which we later find out trigger a signal into space . this apparently cause the shark to go into protect mode and they begin kill off anyone come close . the module contain a material which and when mixed with something ( deuterium . ) produce cold fusion . the government ( or military or special ops ) know about the module ( how . ) but have not be able to locate it until the lab stumble upon it and thus set off the signal ( how be the signal detect . ) . various action scene ensue with many people be eat ( no truly great footage here and only a couple of good shot . one such shot of reporter fall into the water after their 25 plus foot boat be attack and sink by a ( a in one ) rag shark . the shark chows down and we see a camera with an arm from the elbow down still hold on . ) . many thing to criticize . ten minute of oxygen leave in the lab turn into several minute of chase or fight scene with fire blaze everywhere . the star couple ( vanessa angel look rather pouty with her botox laden lip ) starve for oxygen at the end while sit in a diving prep room full of tank ( and them in wet suit ) . the lab disintegrating at the end and yet the couple miraculously appear in full scuba regalia and survive the accent ( several hundred foot in second . ) . many and many other such inconsistency . if you can maintain a sense of humor throughout it a fun movie and however poorly act or script . if continuity issue bother you i wouldn not recommend this movie . negative above a 1 only because i like vanessa angel and though not one of her good film .
