With Maggie Smith in the title role you knew you are in for a fun ride and although there were laugh out loud moments at caustic one-liners it was the sensitive juxtaposition of the van lady's needs with those of his own aging mother which elevated this story. I know for some Mr B is a bit like Marmite- love or hate his writing - personally I love both, thickly spread.

PS Dug out my copy of "Untold Stories" by Alan Bennett and found this gem which will be interesting for those of us that saw the film last night.
