There's an underlaying sense of realism to this series. For instance, the dialogue: as in life, when things are spiralling, there's a lot more said in the silences between people than in the words between people. Kudos to the actors for their restrained and layered performances. A thumbs up for the taut script. Also, I'd add a nod to the directing. This series will leave you thinking after the credits roll. I found myself thinking that peoples lives rarely follow a straight line, and it's not the roadblock that tumbled us to our knees that defines us. It's what we do after the fall.
