Feeling a lot like one of those cruddy bigfoot/sasquatch movies from the '70s (The Legend of Boggy Creek, The Legend of Bigfoot, The Creature from Black Lake), Terror in the Swamp (AKA Nutriaman: The Copasaw Creature) is utterly inept garbage from start to finish.
The majority of the film focusses on either the authorities trying to track down the creature responsible for the spate of grisly deaths in the Copasaw region of Louisiana, or on the hillbilly sadsacks who inhabit the bayou - actual monster action is at an absolute minimum. The result of a scientific experiment gone wrong - a coypu (a large swamp rodent) injected with human hormones - the Nutriaman looks suspiciously like a man in a fancy dress store gorilla costume with added claws. This dreadful regional horror wisely opts to keep the creature out of view, using POV shots, or by carefully concealing it behind foliage.
With ham-fisted direction, a dreadful script, terrible performances, virtually no gore, no gratuitous nudity and no scares, this one would have disappointed anyone unfortunate to see it at the drive-in or grindhouse theatre back in the day. These days, it can disappoint a whole new audience: idiots like me who seek it out on YouTube.
1.5 out of 10, rounded down to 1 for morbidly obese Cajun redneck T-Bob (Michael Tedesco) and irritating swamp hag Crazy Sally (Claudia Wood), both of whom deserve to be ripped to pieces by the nutriaman, but who stay alive.
