Not a bad version of the more famous successor. My version is called "Gaslight." It is the story of a man who marries a young woman and then movies into a house where he had previously murdered an old woman, the elderly aunt of his bride. He is there to get his hands on some rubies that he has thus far been unable to find. He must, in the process, search in other parts of the house. To accomplish this he must feed into his wife's fears that she is going insane. If she is terribly unbalanced, nothing she says is going to be taken as the truth. There is true evil here, and I have to admit, I wanted the guy to get "his." The acting is good. There is tight suspense and a couple of very memorable scenes, especially the scene of enlightenment. One thing that made it hard was that the husband is really mentally unbalanced and it's obvious. He pushes things past where he can control them. But that's a small criticism.
