Hounds of Love
Listen, Hounds of Love is not for the faint of heart. In fact, it's a pretty traumatizing story about a couple who routinely kidnap young girls, use them as a sex object for a week, and then kill them and dump the body. It's clear that the horrors of the film are very graphic and realistic. In fact, they seem to be loosely based on a true story. And while the film is pretty chilling to watch, it still makes for a fairly cathartic experience.
For all the bleak subject material, Hounds of Love is incredibly striking. All of the performances are phenomenal, especially that of Emma Booth, who plays Evelyn White. While the story has enough tension to keep you on the edge of your seat, the journey is what makes the experience bearable. And, at the risk of divulging too much, the end is surprisingly uplifting.
