First,... this is an all new and original badass shark movie !!! Secondly,... this is an all original and new badass girl-power film !!! Third and most importantly,... any time you find yo-self 47 meters down, as a human, you know some ol terrible tragedy terror will be in route directly,... that being said, the cast and the production crew pulled this off GHOSTSTARSTACULARLY !!!! Way better than had anticipated,... as far as action-horror is concerned, this film is a PERFECT-10, executed masterfully, all while being underwater !!! The action is fun and exciting,... then turns to terror & desperation,... and ends brilliantly with some real- old- fashioned GIRL-POWER !!! The killing is fast, brutal, bloody and always unexpected !!! TheGhoststarOriginal watched this entire movie holding his breath with a bad look on his face, rooting for the entire cast,... even the super hot stupid one,...jk Rose Stalone,... The special effects are awesome !!! PERFECT PURCHASE !!! For your shark movies,... and most definitely, worst-case scenario survival collections !!!
