I'm rewatching series 3 as part of a general rewatch. In my opinion, it's got the same brilliant, funny, touching qualities as the other two seasons. If it's not as good as the first two seasons, it's very slightly less if at all. BBC should have stuck by it and let this excellent show continue to its natural ending. I sincerely believe it would have picked up more and more viewers as word spread in the same way as many other sitcoms eg Only fools and Friday night Dinner. It beautifully encompasses a large range of emotions from comedy to drama. What a shame the powers that be did not have the guts to back it up!
