I’m a big fan of Jaume Collet-Serra’s films and this short sharp shocker doesn’t let you down. Blake Lively is the med student who goes south of the border searching for a beach her late mother loved – problem is Mom didn’t tell her there were sharks. Just 200 yards from shore she loses her board and has to try to battle with a very angry guy. Her ingenuity sees her take refuge aboard a dead whale, a rock and a buoy and as well as having to stitch up the huge bite on her thigh while the tide rises steadily, she sees three men killed. Written by Anthony Jaswinski this is paced brilliantly and Lively gives a pitch perfect performance that finally sees her match her surname! Nailbiting stuff. And three cheers for Steven Seagull!!!
