Despite a rough start, things do get enjoyably strange and frenetic during the second half when Madam's vengeful ghost shows up. She scolds men trying to burn her furniture, kills a bird and shows up as a skull-faced apparition spewing blood. During the finale, a completely nude woman with super-long red fingernails does some crazy exorcism dance that goes on for longer than five minutes while some old female mystic beats her with a shoe and spits "black dog's blood" on her! There's also nude body painting, a decapitated talking head, a reanimated crawling hand, a real snake getting chopped up with a cleaver, a guy being beat to death with a stick and ears being ripped off. Toward the end, you might notice a few ideas were pinched from KWAIDAN (1964) and, while nothing great, this Shaw Brothers production is fairly entertaining, lively and colorful, and the whole thing looks pretty good.
The DVD is from Intercontinental Video. A pretty straight genre feature, it was followed by two unrelated comic horror sequels: HEX VS. WITCHCRAFT (1980) and HEX AFTER HEX (1982).
