An excellent little movie, though it might be wasted on anyone likely to get disappointed by 1970s special effects or confused by the intrusion of a plot. It's a well-made supernatural re-working of Agatha Christie's "And then there were None" (Originally "Ten Little Nigger Boys") and starts when the descendents of a 17th century witch gather at an English country house in the hope of receiving part of the family legacy. Instead, they get a dose of poetic justice delivered from beyond the grave. Don't expect to be scared out of your skin, just entertained for a while.
