This was the BBC doing comedy at its best in the 1970's. Written by the marvellous Roy Clarke (80 next year) and with superb performances from Ronnie Barker as Arkwright the stammering shopkeeper, David Jason (pre Only Fools & Horses) as his naive nephew Granville, Lynda Barron as the shapely nurse Gladys Emanuel and a stellar supporting cast, this was as close as situation comedy can get to perfection. Over 4 series this brilliantly comic and well observed show explored every human foible and weakness known to man - and a few that weren't (before viagra there was ginger cake!) and developed cult status. If you missed it the first time, do yourself a favour and see it now. If you already know how good it is, enjoy it again. Highly recommended.
