The greatest British TV show ever?

I watched all/the vast majority the first time round and really enjoyed them, but only now, when re-watching them on GOLD/DAVE/UKTV etc., have i realised how utterly brilliant a show it is. The episode (maybe a special) where nanna dies, is truly amazing.

Its consistency is unrivalled IMO, with a script and characters that are embarrassingly far beyond any current British sitcom. How can Ralf Little turn up to the 2 Pints set knowing how far he has fallen???

WHAT ARE YOUR THOUGHTS?
