I think they did a great job with a tough story line premise. Very interesting and the actors were very good. It begs the question though as to the ending, whether Irene rescuing Franklin is a prelude to a new season. The colony they saw on the edge of the hill - was it here from where Jude escaped? Is it a prison of sorts? Why is there and who controls what people go there.
So I would be fascinated to know where this story could go.
