To better one’s ‘Elf’
7 / 10
When it first appeared a couple of years ago, “Elf — The Musical” fit that pattern. The sluggish, saccharine-sweet adaptation of the 2003 Will Ferrell movie wasn’t bad enough to qualify as a lump of coal, but it didn’t make you wish for a return ticket in your stocking. But there’s been a Christmas miracle on Broadway, because the retooled “Elf” that reopened last night is a startling improvement. Zippier and funnier, the show is now a bona fide treat.
