The Wicker Man is a 1973 horror flick, in text about a British policeman running afoul of an Celtic cult, but in subtext about a modern churchgoing man falling afoul of counterculture hippies. Starring Christopher Lee, it is widely considered one of the best horror movies ever made.
The 2006 remake, starring Nicolas Cage is… less well respected. For good reason.
As a case of adaptation degeneration—the tendency for a sharp decrease in quality when a work is rebooted, remade, or translated from one medium to another—it is very nearly a textbook case. It’s sad to see a disturbing, jarring horror movie remade as a massive bundle of “WTH?” and “FOR WHY?”
If you absolutely MUST watch The Wicker Man, see the original and skip the remake. You’ll thank me later.
