I thought this was quite tense and the small largely unknown cast did quite well.The scenes involving the shark really were excellently crafted and very convincing. 8/10
As I thoroughly enjoyed
The Reef,I thought I'd better check out the directors (Andrew Traucki) previous film
Black Water.
I wouldn't say I was disappointed with this film,but it certainly was not as effective as Traucki's latest offering, main culprit was the unconvincing Croc effects which devalued a few scenes. 6/10
