Dark and powerful movie with some strange elements to it

Rating: 7/10 (4 September 2018)

We have three kids that were once friends and one of them had a terrible event happening in his life. They grew up and followed different paths, but remained acquaintances. This sets the tone for the movie as one of the characters' daughter is brutally murdered.
It's a great movie about investigating this murderer, though it doesn't overcomplicate itself way too much; it feels kinda real. They pretty much get in the right lead kinda fast, actuallly.
In the midst of everything, a creepy call from a woman towards one of the characters bugs me to the point where it gets annoying and weird. So weird that, at one point, I was calling her "names".
A dark ending paints what this movie is all about. A dark and rather emotionless ending.
