It is just a real shame about all the one offs that followed Blackadder Goes Fourth that cheapened it and took the edge of the incredibly moving ending (I'm lookng at you Blackadders Xmas Carol).NinjaDeathSlap said:My choice would be Blackadder. 4 seasons of some of the best quality comedy ever seen on TV. It started off funny and only ever got funnier; and even after all the jokes the end scene was one of the most moving I have ever seen.
OT: I heard the end of Roseanne beautifully dealt with loss and issues of mental health when it tanspires the rather tacky ninth season where the family win the lottery and fulfil all their dreams is in fact a dream as Roseanne drifts into a fantasy world as she can't cope with her husbands death from a heart attack.
Honourable mention also to every British sitcom and drama that didn't outstay its welcome.
