I just binge-watched the series and it was an amazing emotional ride.
The story lines and actors were superb, in both execution and casting. At the end, the lines between good and evil, nature and nurture, heros and villains became quite blurred in my opinion. There was always a 'he's a bad guy but...' or 'she's a hero, but...'. I highly recommend this series but carve out a weekend - you'll find it hard to stop at just one episode!
