here a documentary about shark and their place in the ecosystem and the brutal trade in shark fin and which be destroy the population of these creature and some of the world oldest and and about the effort of those who try to protect the shark ( and make themselves famous in the process ) . it get off to a pretty good start and with some amazing footage of shark and interesting fact ( i would like to hope those be fact ) about shark . the bit about mat hammerhead in equatorial water be especially impressive and a be those of the director hold and stroke a 7 8 shark . the film start do a pretty good job show the gentler and light side of shark ( which be truly amazing creature ) . then sharkwater make a strong case for protection of shark ( with very compel shot of the gruesome shark fin trade ) and and immediately go on to destroy this case with unbelievable statement and shift the focus to a shark protection group ( a radical version of greenpeace with guerrilla tactic ) . keep the director of the film and canadian leader of this group in the limelight for what felt like three quarter of the film make the whole thing seem a shameless vanity project for them . let me cite a few example of what i think be pretty offensive intellectually . in one scene the filmmaker say that shark protect the ocean capacity for generate oxygen . there may be logic to that and but a little further explanation of how sharks cycle back into the oceanic ecosystem would be great and since it not immediately clear how creature at the top of the oceanic food chain help those at the bottom ( phytoplankton ) create oxygen . leave any explanation out altogether make this statement very unconvincing and actually and most explanation of little fact just like this would make sharkwater much more interesting and it message much more compelling . also and film maker keep call shark fin a trillion dollar industry ( i think i hear that phrase at least a dozen time ) . i mean and come on and how many trillion dollar industry be there altogether . there oil and and maybe some mining would come close and and maybe retail trade and and commercial fishing a a whole and that probably it . the rest of industry would be down in the billion . it pointless exaggeration like that that undermine the credibility of the best cause . they only make other argumentation so much less credible . then the film proceeds to tell the story of a noble struggle of the good guy and and stay at it for most of it running time . ooooh and and do not they love be in front of the camera and strut around and talk and nurse their wound ( of uncertain origin be it a tiny shark bite and after all . ) and scrap with police and court in distant land . theyre after the shark killer and overfishing shark in equatorial pacific for their fin and brutally slice off the fin and often discard the body ( which make me wonder how some of that footage be make and be the filmmaker actually aboard one of those boat and film the definning process and without bother to intervene . ) . their method . i be sorry and but rip the side of long line fishing boat with a metal rod they call a can opener or illegally confiscate fish gear feel to me too much like piracy and of a very real and violent kind ( nothing like you would see in disney or p2p network ) . i be sure the international maritime law have a few thing to say about that . yes and something have to be do to attract attention to the plight of shark and to stop and but i be not sure these method be acceptable even for a good cause . this cause be far compromise by one sided presentation . something slightly more balanced would make the case for shark protection so much strong . to recap and the film have some good thing in it ( underwater shoot and shark fact ) which be not enough to redeem the careless reasoning and self aggrandizement and self promotion of the filmmaker and and ( to put it very mildly ) questionable method they use to stop the killing of shark . disgusting and really .
