This is possibly the best TV series I have seen in a long long time. The writing, acting and production are superb, and the stories gripping. If there is anything to complain about, it would be that I wish some of the stories were given more time than an hour each to develop to their full potential.
Technically, the quality of the DVDs were generally good, but I have found some momentary pauses in the middle of certain episodes (about half a second or so each time). I would also have loved to see more behind-the-scenes footage about the production, more commentaries by the writer and director, and perhaps even some interviews with the actors. Still, with a series as good as this, I'd say this dvd set is worth every penny spent on it.
