"The film lasts a mere eighty minutes and, with the possible exception of a fight scene between two men that feels more at home in one of the popular lucha libre films of the time, not a moment is wasted. Though there is nothing original at all about it (in addition to its murderous title character, it has a crippled manservant and a madman in the attic), the film is so tightly constructed, the narrative moved along so propulsively, and the experience of watching it so consistently and thrillingly strange, that it rises above the also-rans to become a minor classic of its genre." - Matt Bailey, Not Coming to a Theater Near You
