Not a new movie, but I re-watched one of the best horror films made, IMO: "Rosemary's Baby." There have been recent versions, but I'm referring to the 1968 film, starring Mia Farrow, John Cassavetes, Ruth Gordon and Stanley Blackmir. (sp?) Directed by Roman Polanski, this movie doesn't have blood and gore; instead it is subtle suspense.
Premise: a young couple, Rosemary and Guy Woodhouse move into an apartment and find out that their neighbors Minnie and Roman Cassavet (Ruth Gordon and Stanley Blackmir) , are involved in witchcraft. Guy (who's an actor) makes a deal with the devil in order to help his career. For example, he gets a highly regarded part in play when the original actor suddenly goes blind. Also, a good friend of the Woodhouse's tries to tell Rosemary that she's in danger, but then he suddenly goes into a coma and dies three months later.
When Rosemary finds out that she's pregnant, the Cassavets convince her to change doctors. The doctor they recommend, Dr, Sapirstein (Ralph Bellamy) , does Rosemary no favors. When she has a severe pain, he ignores it, says that it will go away. He also tells her not to read any books, take vitamins or pills.
Throughout the movie, the audience knows what is happening, and even though Rosemary is suspicious, there is nothing one can do to help her. Everyone is involved in this conspiracy, and Rosemary is left on her own. She eventually gives birth to what is the son of Satan. The baby isn't shown at the end, except for his strange eyes. But you still get the message loud and clear.
I give "Rosemary's Baby" an "A" Good acting, suspenseful where one really feels for the characters. If the movie does nothing else, it reminds you to be careful of new neighbors.
