black water and co direct and write by david nerlich and andrew traucki and be very simple in it execution yet effective . the film be a low budget australian movie that will unfortunately not get the recognition it deserve because as far a creature feature go and this be one of the best out there . the setup be rather basic while grace and her husband adam and her young sister lee be tour some mangrove in the northern territory when a saltwater crocodile flip their boat and leave them strand in the tree . the whole movie be about their survival while the crocodile be lurk below wait to strike . unlike greg mclean rogue ( another killer croc movie release earlier in 2007 ) and black water be not about the audience have fun guess who gon na be eat next and it be about hop and pray that the three people will get out safely . the three unknown actor do a great job with pretty demand role and consider it be film on location with a real crocodile instead of cgi . the character act realistically in the situation and the dialogue seem natural and not force . suspense be build up throughout the entire film and we do not see a lot of the creature but just know it be near be terrify enough . this be edge of your seat stuff and highly recommended if you enjoy original and ( most importantly ) scary horror film . 4/5 .
