Really enjoyed this one. It's a nunsploitation version of Franco's earlier Justine (1969). Like with most of the E. C. Dietrich productions, it leans heavily towards exploitation and doesn't have quite a lot of depth for its subject matter. Nevertheless, it's a really sumptuous film with beautiful cinematography and music. The cast is especially good.
The marriage of Grimm-like fairy tale and nunsploitation is strikingly effective in making you see what institutional religion is trying to destroy. Susan Hemingway's natural innocence, representing our uncorrupted selves, elevates this film far above others of its kind. Beautifully shot - this is, along with MISS MUERTE (Diabolical Dr. Z), Franco's best. Superior in its austerity to the extravaganza of THE DEVILS.
