I don't think I ever saw this when it was originally broadcast but now, thanks to the magic of Freeview, I have been able to watch most of the first two series over the space of a couple of weeks.
And I still haven't come to a decision about it. I do recall seeing William Gaunt in a more recent sitcom with Penelope Keith (Next of Kin) in which his role was essentially that of feed to Ms Keith, but with occasional opportunities for pathos which made me wonder how he would be as the centre of a sitcom.
