The more he sees, the less he understands

"You've got fake biology, fake religion... Sir, have these children never heard of Jesus?"
Christianity collides with Paganism in Robin Hardy's 1973 British thriller "THE WICKER MAN," which I watched today.
A mainland Scottish police sergeant (Edward Woodward) visits a remote island to investigate the report of a missing girl. As his investigation deepens, he finds himself immersed in a community bound by strange rituals and beliefs that horrify him.
A visit to the island's chieftain, Lord Summerisle (Christopher Lee), merely confirms his worst fears: The island's inhabitants have shed their Christian beliefs and turned to the power of human sacrifice instead.
"The Wicker Man" is a supremely creepy movie whose reputation was harmed somewhat because it was poorly remade in the 2000s.
I like the original because of its inherent contradiction -- the more Woodward's character investigates, the less he understands about the insular world of the island and its inhabitants.
It's an absorbing film.
