"The Brotherhood of Satan" starts off really well, like Antonioni gone horror. Lots of silence and lengthy tracking shots about nothing, and the script perversely takes 20-25 minutes before any of the situation begins to make sense. But then the story turns into a fairly standard Satanic-coven flick, and is nothing to get excited about. If you made a pie chart for this film based on how much the actors get a chance to ham it up and flash their chops, it would be 98% for Strother Martin and 2% for everyone else. I didn't realize this until after the film was over, but the main little girl is played by Geri Reischl, who later became the "substitute Jan" when the Brady Bunch attempted their infamous musical-variety series. Surely, Satan played a role in getting that show on the air.
