For a B movie it gets a B+ in my book... Slow to start as you get introduced to the hero, the heroin, and the victims to be massacred, it's worth a watch as it rev's up into gore and horror mode, then enters the hero Rambo style to take down the mutated hordes. Lot's of blood and gore in the tradition of slashers, zombie flicks, and Rambo, but the FX are acceptable. More of an action horror movie than just a horror movie, but the butcher scene was pretty good. I'm gonna be generous and give it 5 Stars, coz no matter what others say, it's worth a watch.
