i watch the unrated version of this movie and a a person who have study the life and crime of speck closely and i must say this movie be a flawed but ambitious take on the real story . while capture the true horror of speck and the murder this film make the following factual error . 1. speck do not inject drug at the crime scene a depict in the movie . in fact he be mainly an alcoholic and pill popper who rarely take drug via syringe . 2. the asian nurse who survive speck massacre do not squirm her way down stair and under the couch in the living room a depict in the movie . this would have be impossible . in real life she hide under a bed while speck methodically eliminate his 8 victim . 3. the movie depict speck a be violent and brutal with the woman as soon a he meet them . not true . in reality speck be at first calm and gentle and reassure the woman he wasn not go to hurt them . this be how he be able to tie each of them up . 4. the real richard speck be not the deep thinker the movie depict him to be . fbi profiler robert ressler interview speck in the 80 and say that speck not only didnt know why he commit the murder but that he wasn not interested in learn why nor could he shed any light on why . speck be know to be of below average intelligence and not the philosopher king who narrate this movie . if the story wasn not so tragic and horrifying and the voice over would be laughable . all in all and doug cole performance be adequately menacing and cold blood even though i do not think the real speck be so forward in his violence . no doubt he be a very violent person when under the influence but he be also know and after all and for be a fairly slick con man who be able to put people at ease before victimize them . beverly ann sotelo performance a the survive nurse be the fine in the film . she be a very good actress . if you be at all squeamish and do not see this film . it very graphic and disturbing .
