The creator of this brilliant five-part series has gone on the record stating that they would not rule out there being a second series. It's really hoped that would happen. And if they would be able to pull it off with anywhere near as much intense drama as the first, it would be a truly remarkable achievement. For without a doubt, this is some of the finest programming you're likely to see this year (or for that matter the past several years). The entire cast is outstanding, and Suranne Jones is just simply phenomenal... all acclaim she receives is so well deserved. This is one for the library.. and that final episode, in my mind, will go down as one of the best series finale's in programming history.
