Sadly but predictably,'Allo, 'Allo has faded from our screens due to its 'racist' characterisations. The same fate, much more deservedly, befell It Ain't 'alf 'ot, Mum.
I never personally rated Only Fools and Horses, having had enough of Cockney ne'er-do-wells in Minder. I had the same malaise about the over-praised Birds of a Feather. To me, David Jason will always be the hapless Granville of Open All Hours, the definitive Dangermouse and Mr Toad and the world-weary Inspector Jack Frost.
I'd have rated Last of the Summer Wine higher, but as a Yorkshireman that's to be expected. That said, it did go a little downhill after the glory days of Compo, Clegg and Foggy!
