Female Convict Scorpion is a 2008 Chinese Japanese film called Sasori in Japan. It's based on a manga and a 1972 movie. A woman is forced to kill her boyfriend's sister or the villains will kill the boyfriend. She goes to jail and becomes a monster. She escapes and starts getting her revenge on the people who forced her into her current situation. It's an arty film with a bit of a weak script, I often felt myself wandering out of the movie. The last third, mostly revenge, is the most interesting part of the movie. That's we learn much of what the story is all about. It gets a 4.9 on the IMDb, I gave it a 5, but I wouldn't give it a 6.
Mary, Mary, Bloody Mary is a 1975 movie that was directed by Juan López Moctezuma. He directed The House Of Madness, or The Mansion Of Madness, which about inmates taking over the mental institution. I had seen that and it was weird enough to stand out. This is pretty weird too.
Cristina Ferrare play Mary, a bisexual blood drinker, maybe a vampire, who drugs people, often during sex, slashes their necks, then drinks the blood that gushes out. Mary's an artist who drives a VW Minibus and on her travels she picks up a guy for a lover.
John Carradine plays her long lost father. He kills the same way as Mary and the bodies are starting to pile up. There's some cops trying to figure out who the serial killer is and Mary and her lover are suspects. Things go sour for Mary but she has a happy ending riding off in her VW van. More entertaining than our first movie by a fair bit. It scores a 5.3 on the IMDb and that's about right with me.
