Let's face it, almost everyone who writes on IMDb likes to claim such-and-such is the best movie/TV series/mini-series etc. Well this is my pick. I can only assume that not many people have seen this because there are some fairly mediocre programmes getting the nod. This show was a dark black comedy with exquisite scripts and terrific acting. It's the best British show I've seen (Upstairs Downstairs is close and I accept The Singing Detective may be better than I found it). If you get to see reruns of this - make the effort. You'll never regret it or forget it.
Update: the first series is now available on DVD, which is great news. It's truly a programme to treasure. How many others do we buy that we never return to? This is such a literate and witty show that it's worth keeping. The only thing is, Series 2 was probably the best and it's not yet available.
