Deep in the ocean some foolish marine biologists accidently disturb an ancient prehistoric creature from its slumber. The creature is understandably a little cheesed off and proceeds to cause the death of many of said biologists. With your brain safely checked in with the cloakroom attendant this film is undemanding and fun. The creature is particularly impressive and credit must go to the the special effects guys. The cast is eclectic and low budget with Miguel Ferrer giving the best performance as Snyder, the only member of crew realizing the gravity of their situation and slowly going stir crazy. This film is better than many other watery efforts and this includes bigger budget efforts like Leviathan and Sphere.
