identity be an above average horror film and i be always root for b movie filmmaker when they break into classy material ( the writer of jack frost 1 and 2 ) . while listen to the director comment on the dvd make me appreciate the film more i be go to review base on the feeling i have walk out of the theater . identity start off with greatness and if you do not watch the last chapter you would get a much good film . i understand what the writer and director be try to do with the end but it take a high quality horror film and shot it in the foot . the film present a interesting idea for a story that i will not give away for people who have not see it . john cusak have a really strong performance the kind that be brilliant in a way that never get notice . the cast be strong and with quite a few big name actor who seem willing to be wet for week . the film be in a genre that the director refers to a single location horror . panic room and phone booth be well recent film in the same vein . classic include rear window and alien . the confined space provide a lot of the tension . worth a watch .
