Movies based on true stories always have my preference, certainly if it's about true crime and serial killers. I had never heard about this story before though, so it was a surprise. They probably embellished the whole story a bit so it felt more fiction than non-fiction. I really doubt that it went like this. That said it was pleasant to watch, mostly because of the good acting from Jacob Elordi and Zachary Quinto. The chimpanzee looked a bit fake but overall it was okay. Not a lot of action considering it's about a serial killer, and a rather slow pace, but still good enough due to the good acting.
