For all the knocking it is taking, Applause is a very good star vehicle especially if your star is not a strong singer. It is a vehicle, nothing more, and is designed to mask the star's short suits as much as possible. Since Bacall can't really sing, can only move well at best and plays herself very well, the show is weak especially the score. It is not unwatchable, just extremely good mediocrity.
If you saw Bacall in the theatre, you might rethink the non-charisma idea. You couldn't take your eyes off of her. Part of that was costumes and lighting, but she looked great. The rest of the cast was not exactly chopped liver either.
She worked her ass off too. Never missed a show and that was a year in town and a year on tour plus I think the West End.
[I'm no fan of Bacall's off-stage. Her rep is that of a nightmare, a nasty BB, but onstage is another story.]
Is it a good show? Not really. A bad one? Oh, no, and fairly easy to sit through provided the star is good. The worst musical to win Best Musical? Oh, please, not as long as Cats, Passion and Hallelujah, Baby are on that list.
The CD remastering is great by the way. One of the best.
