This is a very chilling movie based on an even more chilling novel. It does seem to be a cross between "Oedipus Rex" and "Lord of the Flies" as some reviewers have astutely pointed out, but it is actually based on an obscure Japanese novella. The original story had a Japanes protagonist and was set in a Japanese fishing village. The filmmakers don't entirely succeed in transplanting the action to rural England and casting a Kris Kristoferson in the lead role, but an international film never could have gotten made at the time with a Japanese lead, and once they cast Kristoferson, setting the movie in a Japanese fishing village would have drawn the inevitable charges of racism from the perpetually outraged idiots in the "PC" crowd.
Besides the awkwardness of the adaptation is redeemed by some great acting. This is probably Kristoferson's second best role after "Pat Garret and Billy the Kid". Sarah Miles is also very good as the lonely widow. Her sex scenes with Kristoferson are very erotic if very perverse (you see them only through a peephole as her disturbed son watches). The British child actors are also very good for a change, particularly the very disturbed but nevertheless sympathetic son and the truly psychopathic leader of the gang of schoolboys he runs with (who make the "Children of the Damned" look cute and cuddly by comparison). The scene where the gang eviscerates a live cat is almost unbearable to watch. And the final scene on a hill overlooking the sea is chilling, tragic, fatalistic, beautiful, and mythic all at once. This is and haunting and unforgettable movie.
