I must say I loved Open All Hours with a passion. But this reminds me of the latter stuff from Laurel & Hardy when they were JUST TOO OLD. I personally think it is time to retire off a certain actor in Still Open All Hours to freshen it up a bit. There is just no way Granville would have aged that way to my mind. If people like it though, all well and good. Audience knows best!
Oh, wait a minute the audience thinks it's shit too.. ah, erm, well.. it's got David Jason in it, so he's a 'banker', so an easy choice for a Producer (who is clearly well worth his salt) ... to make ... nothing like 'merit' being the parameter of choice..
