“Frankenstein’s Army” is a found footage film about a unit of Russian soldiers who are fighting Nazis during WWII and searching for other missing Russians. Instead of finding missing soldiers they are forced to fight an army of “steampunk” monsters that have been created by Dr. Frankenstein, who apparently has been attempting to end the war by combining equal halves of communists and fascists brains.
Sometimes, it’s nice to have a bad guy that everyone can hate. In horror, you often want people to root for one person or group and against another, and it becomes troublesome to create three-dimensional villains that have real-life motivations and reasons for the awful things they do. When faced with a situation like that, one of the tried and true solutions is to bring in the Nazis.
