Terrible story; the whole sister’s murder storyline had no bearing to the rest of the film and was a pointless addition. All the characters were unbelievably annoying and by the end I didn’t care if all of them were eaten by the shark. The incredibly slow paddling and even slower swimming was excruciating as we’re the frequent flashbacks to the sister’s murder which wasn’t even witnessed by the main character and yet she relives it as though it happened to her. I’ve watched pretty much most of the shark related thrillers and this is by far the worst. Avoid!!!!
