Just saw the West End production and it is a cracker. Needs a bit of work but it is funny, moving, tuneful, propulsive, thought-provoking, and beautiful to look at. The special effects are tremendous and Andy Karl is giving a bona fide star performance. This is something very special, and I can't wait to see it again on Broadway.
Any season that can field this, Dear Evan Hansen, Natasha Pierre etc., Bronx Tale, Anastasia, plus revivals of Falsettos, Dolly and Saigon is looking like a fine one for musicals.
