now , lets first look into the history of shark films .
there was the unforgettable jaws .
the exciting jaws 2 .
the rather flaky jaws 3d and sometime in the late 90s
another film of the same genre that i ca n't seem to recall ( about the son of jaws returning to wreak revenge or something like that ) .
now , with the magic of cgi , one shark is simply not enough ; in deep blue sea , there are 3 big , mean and really smart ones !
russell frankiln ( jackson ) visits aquatica ( a sea - bound research center ) , where a research is being conducted on the extraction of a hormone substance found uniquely within the shark brain that can cure and reverse the effects of alzheimer 's disease .
the substance is small in quantity and because of this , lead researcher dr .
susan macalaester genetically alters the shark dna and grows them twice the size with brains as big as humans , naturally producing more of the much treasured hormones . as sure as the sun sets in the west , a shark breaks lose and wreaks havoc within the facility during a hormone extraction procedure .
with the flexibility offered by cgi , the sharks get more full - length screen time as their predecessors did in those remote - controlled rubber suit days .
gone are the days of people getting pulled under the water with the water turning red right after .
this time , we get to see the entire gobbling action , with floating limbs and all .
so - so acting , expected in most of your average action film .
jackson ( fresh from his jedi master role in the phantom menace ) , takes on the dark - side force of a different kind and fits well with his wise - cracking lines .
ll cool j 's cook role as preacher , does for this film what steven seagal 's cook could only dream to achieve in his two under siege films .
deep blue sea does not offer any of the psychological thrills that jaws has to offer .
it does however , prove to be a refreshing follow - up within the genre , full of visual thrills , suspense and believe it or not , humour !
its like jurassic park under water .
nothing too stressful
, pure entertainment .
renny harlin , you are forgiven ( for making cutthroat island ) .
a refreshing follow - up with the flexibility offered by cgi pure entertainment takes on the dark - side force of a different kind and fits well with his wise - cracking lines
