Overall, the action here isn’t as taut as it was in “The Reef,” and the shark effects aren’t as impressive. Still, for the most part the movie delivers what it promises.
Traucki manipulates the suspense competently enough, but this film mostly depends on tedious jump-scares for its effect, and has a few too many scenes where someone looks around in terror at the water with a worried expression.
The best movies like this do a much better job of selling the building terror, the fear of a gruesome injury or death by being eaten alive– drowning in the process.
