This series continues to do all the things it does well and extends the basic concepts that were introduced in the first series. With such long episodes and short seasons the writers can give afford the time to do interesting scenes and moments without having to come up with so many plots – compare for CSI. The guest stars excel in their roles (Fay Ripley being a definite stand-out) playing an array of personalities. The twists and turns of the plots are pretty well signposted and not often a surprise, but this just makes it a very comfortable show to watch. Lots of fun, I’m glad I bought the first 3 seasons all at once so I don’t have to stop in between!
