Lethal Dose is a tedious excuse for a horror film, with characters you won't care about and a script that will put you to sleep. It revolves around an animal rights group that tries to rescue one of their own a year after they abandoned him during a raid. What they find is a mix of bad dialogue and pseudoscience.
The film is nowhere near as gruesome as its subject matter would suggest. The opening credits show photos of animals being experimented on, leading one to expect a violent piece of gorn. Instead, we get a bunch of poorly thought out science fiction mumbo-jumbo as our protagonists confront the results of an experiment gone wrong.
This might have been a decent film anyway if we had had some characters we could care about, but these people are stupid even by horror movie standards. It's hard to see how these activists avoided getting caught on their first raid, as they wore only some camouflage make up on their faces even though they knew they were on camera. Furthermore, they decide it is a great idea to smoke pot when they are in the middle of a mission in a government installation. At least slasher movie victims have the excuse of only being at a summer camp when they act like idiots.
