The film works on multiple levels — as a supernatural thriller (though explicit paranormal elements are limited to a hallucinatory dream sequence and the final shot of the baby's eyes), as a psychological thriller about a paranoid pregnant woman who imagines herself at the centre of a conspiracy, and as the
last word in marital betrayal, since the most
despicable villain here is surely Guy, who allows his wife to be raped by the devil in exchange for an
acting role.
