I can't really see the point of this.
The popularity of OFAH is something I could never understand. IMO, it was a slightly above average sitcom in the 80s, but went rapidly downhill in the 90s, and the final few years' episodes were just embarassingly awful.
That Green Green Grass show was pathetic and this just looks like more of the same.
Why not use the budget they've spent on this on a brand new sitcom, with new writers, performers and ideas?
Who knows, it might actually be the next 'Fawlty Towers' or 'Young Ones' or ***insert other groundbreaking series here***
In America they constantly try out new sitcoms with writers/performers who have never worked in TV before.
Admittedly, most of these shows are crap, but every so often a 'Seinfeld' or a 'Larry Sanders Show' will make it through.
Surely the BBC should take a risk occasionally.
