And here I thought he died b/c he rejected their religion.
Britt Eckland's "come hither" song must've been hard to reject, don'tcha think? That is one of the most
erotic scenes I can think of in cinema... Then, the cop's confusion and innocence, his "deer in the headlight" stance in response... The rest of the time he is the straight man of christianity against an island of pagans. He became the offering, just as a bunny or a lamb might to another pagan religion... Maybe it's more of a thriller than a horror movie?
Now, are most American horror films selling puritanical sex ethics? Perhaps... Whether accidentally or intentionally, the subliminal message to teenagers and young adults (who make up the largest portion of the audience at any horror show I've ever been) is that "slutty girls and jerks get offed." Therefore, believe it or not, many a 15 year old will think twice before deliberately being slutty or jerks to others.
Contrast this to "Wicker Man," which was made in the early 1970s, the age of free love. The character who didn't believe in free love got himself sacricficed. Hm, maybe it was commenting on the times? What other horror films were made in the early 70s? I can't think of any. But, consider the behavior of characters in "Easy Rider," or "Five Easy Pieces." The morality was shifted during that era, at least in the U.S. Perhaps also in Great Britain.
