this movie be crappy beyond any limit . it incredible a very bad ripoff from jaw and other ( well ) shark movie . a really bad one everything be really pathetic . the story be pure crap and actor be bad and effect very cheap and no creativity whatsoever . it look like some really debilitated child take jaw script and arrange it randomly and then it parent take their 8 mm camera and shoot the movie with their neighbor . the music be really inappropriate and just some elevator music and bland and overly optimistic when nothing happens and then slightly less optimistic when shark be around or when child get depress ( again listen to very loud elevator music ) . carlo maria ( the author ) should be so ashamed he should ask for his name to be erase from the title . the movie act a perfect demonstration how crappy music will destroy any scene which be suppose to be thrill . there be one major difference to jaw though represent in the beginning of jaw there be comment about stupid people who try to kill shark with dynamite . well and there be an attempt to kill a shark with dynamite . when this do not work and guy take an big load of dynamite and spent like 1/4 of movie by place explosive in some sunken ship . this be really original way to catch the fish i have to admit . they use so much dynamite like they would try to kill a battleship ( i would guess bismarck class of battleship ) or to dig another panama channel . this be just incredible . i be glad they do not try to use napalm flamethrower or tactical nuclear strike to eliminate this bad and bad approximately 2 m shark . well and there be mystic disappear native indian ( who look like german pensioner ) too in this mess . this be not a movie and this be a warn example how bad the movie may be . a a warning it be useful . but the public should be protect from this crap . most of italian movie be bad and but this . this be really exceptional in the bad sense of the word .
