I first came in contact with this story through the drama Signal (2016). That peaked my interest into seeing a movie dedicated to this case specifically.
Eventhough I already knew the outcome of this story, I still found this movie very interesting.
The cinematography was great, likewise with the acting.
I have heard that some consider the pacing a bit slow, but to me the story developed at a rather pleasent and natural pace.

I would highly recommend this movie to those who enjoy crime/true crime and movies with older settings, as this was set in 1986.
