When ALW is good he's great, but when he's bad it's terrible. Not terribly interested in seeing Cinderella until I hear other reviews. It's a tired concept. If it's something like & Juliet then maybe I'd be interested as that was good. Depends on how much Carrie embraces the new theming if that's how it goes.
I saw Joseph last summer at the Palladium and it was good fun. The big names of Donovan and Sheridan Smith got attention but were outperformed by the rest of the cast for sure.
Miss Saigon is by Boublil and Schonberg, who also wrote Les Mis. Les Mis is my all-time favourite musical, but it is very traditional and Hamilton is way more impressive as a spectacle.
