The demise of Brooker and Jones as a writing team continues apace, it seems. The last series of Black Mirror was a huge let down. But where that show had glimpses of the brilliance that made the writing partnership so hugely succesful, this has none. With a script that sounds like a YouTube try out written by a couple of sixth formers, it might raise a smile in a teen audience. But clever satire it ain't. Give it a miss and remember Grandad the way he was.
