this movie be good relatively during the first part of it . we have a story and from 3 point of view . so let find some clue and complete the story . oh wait . none of that stuff matter because the fbi guy be the bad guy . though that be a great twist . it be almost a terrible twist . i immediately downgrade the film from a 7 maybe 8 to 3 base on the last 10 15 minute of it . do anyone else not see why the twist be so bad . yes and it a good shock . but it be bad because it have absolutely nothing to do with the precede hour and twenty minute . there no connection to the killer . the killer be in about all of 5 minute of this movie ( a killer ) and the two fbi agent be only in 15 minute of the previous hour and twenty . we get it . surveillance . oh and the killer be voyeur . which make no sense and because they be only describe in limited term a just be psychopath . and the hour and twenty minute of surveillance we be watch of the 3 story go out the window a everyone be dead in 5 minute . all of this make the end even more ridiculous . oh and they kill a bunch of fbi agent in the beginning . what fbi agent sleep together . all in the same room . to be find and murder by amateur and then impersonate by people who know nothing about be fbi agent . a cop 3 foot away apparently can not hit either one with a standard police issue pistol that can shoot several shot . i hate movie that try to make you feel like this could be real when they make absurd leap they think we will believe . the other thing be the movie end about 10 15 minute after they be reveal a the killer with a girl standing in the field somewhere .
