george zucco be like boris karloff in the fact no matter how poor the film he appear in be and he would always maintain a sense of dignity and turn in a fine performance . the mad monster be no exception to that rule . it be by all standard a poor ( if entertain ) film . the filmmaker obviously do not know how to make the most of their low budget and the script seem a if it be turn out in one or two day . still and zucco be fine and believable a the mad scientist . the film itself be enjoyable on a camp level . normal horror movie fan for the most part would not take a liking to prc film . however and these poverty row production have a small but loyal cult follow . occasionally they would rise above their limitation with detour be the best example of this . usually they look like this . for all it technically poor quality and the mad monster be an amuse enough way to kill a rainy afternoon . the dvd from retromedia be recommend and a it pair this with another prc production the black raven and the original theatrical trailer and and best of all an interview with glenn strange talk about his role in this movie . ( 4/10 ) .
