Having won a Tony Award for Merrily We Roll Along, Daniel Radcliffe returns to make more magic in the Broadway premiere of Duncan Macmillan’s interactive dark comedy about a British man who makes lists of the world’s good things, at first to ease his mum’s depression and later to temper his own. The show ran Off Broadway in 2014 with Jonny Donahoe, who also contributed to the script; this version is co-directed by Macmillan and Jeremy Herrin (Wolf Hall). It’s theatrical candy cane: slim and sweet, tempered by sharpness and striped with bright nostalgia.
