Wicker Man does for paganism what
Jesus Christ Superstar did for Christianity, namely dumbing down the tenets of the belief system for hippies and setting it to painfully bad music. A totally square copper investigates the disappearance of a young girl on an outlying Celt island. There is more outdoors fucking on Summersisle than in a Zola novel, and quickly Detective Howie realizes that the residents are practicing that
really old time religion. They play him for the Fool, literally. Christopher Lee hams it up, and Brit Eckland can't act, can't dance, and definitely can't sing, but she's very skilled at being naked.
Belongs in that groovy class of unscary horror films which includes such classics as
Let's Scare Jessica to Death,
Equinox, and
Season of the Witch.
