I must reiterate what's already been said. The 2 series available on DVD are brilliant and the last episode in the second series actually made my mouth open as the twist (regarding one of the bedroom's characters) was so amazing and unexpected. There are however quite a few instances when the microphone boom can be seen in shot and in another scene, you can make out the shadows of the camera-person as he/she tries to step away when the action moves from one place in the room to another. All that though adds to the charm of the piece. The acting is uniformly excellent throughout but a special mention must go to Alun Armstrong who is just the most brilliantly diverse actor, so believable.
