Rectify

This, whilst produced by the same people who produced Breaking Bad, doesn't have tense, action and the characters aren't under constant threat. Rectify is more of a character-study than a deep narrative, there isn't a giant mystery or conflict it strives to describe a much more personal experience of the protagonist, and does so wonderfully. It is about how one man deals with life outside of prison walls after serving 19 years within them, he is released with no smooth transition and is literally thrown into a world he doesn't understand. Rectify is about a man who has been left stuck in the past when the world has changed so much without him. The production values, writing and cinematography are all on par with Breaking Bad's extremely high standards.
