Pretty macabre and creepy, highly recommended.
I enjoyed this hugely after recently purchasing the DVD. The key to its effectiveness are some of the indelible images present (the horse and carriage surging into the foggy night, the witch's portrait, the clasping hands behind the curtains etc.) Its mis en scene really got to me and the narrative pacing is very good (the picture certainly moves along hastily). The dialogue is at times a bit unsubtle, but overall I found myself completely swirled up in this eerie tale of witchery and vengeance. A cornerstone 60s horror film in my opinion.
