Only a Scrooge would snub Mum’s List, a heart-wringing, grief-stricken British weepy, adapted from the bestselling memoir by St John Greene. Rafe Spall does sterling work as a West Country widower, left to pick up the pieces. Emilia Fox is his late wife, Kate, who lives on as a guardian angel in the form of her texts and Post-it notes. Director Niall Johnson takes her scattered life lessons and makes them into a collage or possibly a soufflé. It’s warm to the touch, slightly soft in the middle.
