Santa Sangre
It's pretty much impossible to explain an Alexandro Jodorowsky film to anyone, but this movie is a little more coherent than usual, and does have a plot that you can follow. Here's the plot:
A husband and wife own a circus. The husband starts messing around with a tattooed woman who also works for the circus. In a jealous rage, the wife throws acid in the husband's crotch. This angers him, so he cuts her arms off and then slits his own throat and bleeds to death. This pretty much puts an end to the circus. The couple's son witnesses these horrible events and must be put into an insane asylum due to the trauma. As an adult, he escapes from the asylum and reunites with his armless mother. She takes over the mind of her son, and uses his arms as hers. In other words, he spends most of his time standing behind her and sticks his hands in front of his mother as if his arms actually were his mother's. And these two (the son is actually Alexandro's son) do a brilliant pantomime act. In one scene, she feels like playing the piano. The mother sits at the piano and "plays" while the son actually works the keys. This is amazing to watch.
Unfortunately, the mother also has revenge on her mind, and now that she has arms again, she has some unfinished business to take care of, like killing that tattooed lady who caused all of this unhappiness. So, the evil mother leads the son on a bloody rampage of revenge, until the son somehow finds the mental strength to break away from his mother's control.
So, that's your basic plot, but the movie is filled with amazing visuals, an incredible use of music, many incredibly bizarre scenes, and other subplots. I'd say it was one-of-a-kind except that Jodorowsky has made other movies. Jodorowsky's unique vision makes for an amazing viewing experience. I'll give the movie a rating of 5.
