bobbi, the inclusion of a BLM reference is not the first of its kind. In 2005 the Dibley special included the cast watching an item on starving children on Geraldine's tv set.
I was wondering how good a special this year would be with 4 of the main cast having died. I know Letitia was written out before the death of Liz Smith, and we have also seen the passings of Roger Lloyd Pack, Emma Chambers and John Bluthal.
If the storyline includes Dawn eating vast amounts of chocolate in lockdown I don't think that would entertain me. But the inclusion of BLM is another good reason to find something else to do during transmission.
I have no idea if DF would have felt the same had she not married Lenny Henry nor adopted a black daughter, Billie.
