Just finished watching this season and happy to report that it's up to the usual standard. Whilst some reviewers describe it as dour (which I understand) I've enjoyed all the seasons and Henshall, Bonnar et al make a fine job of it imo.
It's as good as shows such as Vera and Broadchurch and I'm looking forward to the next season in view of the twist in the tail.
