Ben Parker's feature directorial debut never takes full advantage of its small setting, resulting in a grim thriller that isn't as compelling as it might have been in stronger hands.
This B-movie thriller fails to go beyond its familiar underwater peril tropes, providing as nearly a claustrophobic experience for viewers as its characters.
There’s a modicum of suspense, the sense that not all will survive and casting that gives away who has the best chance. It’s a shame everybody involved, including self-righteous Matts, is so unpleasant there’s nobody to root for.
