Reviewers from Rotten Tomatoes have praised the film's use of practical effects and gore, though some noted the plot is straightforward creature-feature fare.

A group of eco-terrorists breaks into a secret lab in the jungles of Bali, only to discover a genetically enhanced long-tailed macaque. Unlike King Kong, this monkey doesn't want to climb the Empire State Building. It wants to mimic you—and trap you in your own reflection.
