after you have see enough movie and there be very little that doesn not remind you of other movie . nevertheless this be a watchable if somewhat disturbing film . i have to shut it off from time to time and come back to it later . like silence of the lamb it feature the search for a serial killer who have abduct someone and have confine her to his chamber of horror and like flatliners the main character explore a dream world through an experimental procedure . the surrealism of the dream sequence be what make this film and a one find the character in a situation and landscape in which literally anything can happen . and beyond this continuity and make sense be not necessary and which make it a film maker dream too . the only thing that seem a bit off be the fact that in the end one hop for the redemption of the serial killer or the exorcism of his demon . you actually feel sympathy for the little boy inside the man and but clearly the innocence of the boy can not be separate from horrible deed of the man . the focus swing a it must from save the man to save his victim .
