This film spoke to me for a couple of reasons. I was a college student during the time depicted in this film, and I remember very well how naïve many young women were about how manipulative, conniving, and dangerous some men could be. I'm fortunate that nothing happened to me, because I certainly took some risks in situations where I should have known better. And then when something like a sexual crime did happen to a young woman, law enforcement didn't always take it seriously. They often thought the girl was asking for it because, for example, she was wearing a short skirt and walking alone at night.
The pacing of this film is deliberate and intense, and it switches back and forth between time frames and victims. I found it a little annoying at first, but it all made sense at the end. I thought Anna Kendrick and Daniel Zovatto played their roles extremely well. Zovatto came across as creepy AF. A few points are fictionalized, of course, and I'm not sure how much. I did some reading about Rodney Alcala, and the way he was apprehended is essentially accurate. If you can deal with the slow pace of this film, it's well worth the watch.
