This was an almost perfect work - the writing and the acting but also the camera work, the production design and the directing. It is a pity that the BBC didn't promote it more vigorously. They must bring it back soon and make sure a much wider audience see it. You simply don't get TV of this quality any more. It sets a yardstick by which all other TV drama will be judged for the next few years.
It is extraordinary that all those concerned suddenly appeared - and produced this beacon in a sea of TV dross. The only previous credit I recognised was the Cameraman for the hugely underrated film "Ratcatcher" - which I also recommend.
