Shark Night 3D Film Reviews : PG-13 is a warning to the operation of horror-dogs: Night Shark 3D provides no sex, no nudity (except a bare ass guy) and very little gore. But the note is not far from sufficient warning. It also lacks the tension of a good horror movie, or the mood of a self-conscious being fun bad. Even at the height of at least the title promises: Not enough action for sharks, which takes place mainly during the day and 3-D is said in a couple of shots of fire.
