Remarkably successful at creeping out the audience. Perhaps the thing I admired most about it is that the movie stares right back at you. Most ghost/horror/suspense films show something shocking, then quickly cut away. The Innocents doesn't. It lingers on and doesn't allow you the safety of looking away (it makes you do it yourself). The sexual aspects of the film are also handled well: the issues are discussed but the details are not.
Unforgettable scenes: the boy's poetry reading and the woman in the lake (I still shudder thinking about it).
