identity be a very good idea how a horror thriller should be do . it achieve very much suspense from the beginning till the end . there be many puzzle to solve but it keep you anyway ask if there be a logic for all these victim . here be perhaps the weak point of the movie but hey it be just a movie and that must not be always a realistic one . if you have enough fantasy and imagination you can enjoy it . i think the director develop the story deep enough or too much . perhaps some scene could have be delete . i have to admit that there be a surprisingly end that let even open for a sequel . picture be well do . i warn you there be many bloody scene and much violence and be not an usual thriller . rating represent 6 . 75/10 . film to recommend in this genre be no doubt the both final destination and i know what you do last summer or joy ride .
