For decades now there have been movies that are so bad that they are good. Mutant Girls Squad 戦闘少女 血の鉄仮面伝説 (Sentō Shōjo: Chi no Tekkamen Densetsu) is one of these movies. As with most (but not all of these types of movies) it’s science fiction and bad science fiction.
Although I think the movie is worth seeing there is one caution that you may wish to know of: there is blatant male fan service in this movie. Amongst the least offensive male fan service is the girls are often dressed in classic male-favored for women to wear cosplay.
