I think this film highlights decisions that people have to make in life death situations. The isolation of being in the ocean with miles of the unknown below where you swim, where currents change and waves are constantly battering against you is everyone's worst nightmare and then of course comes sharks. There was a lot of tension in this film and given the small cast they were all excellent in their roles and were very convincing. Nothing in the film felt fake and of course the footage of the sharks were real. This film is well worth a watch.
