Based on a preview 3 weeks ago which, granted, is a long time:
Some, but not all, good songs;
Talented cast;
Good costumes and lighting;
Not unwatchable.
The book is badly plotted and then badly written. Trite;
The choreography is uninspired; I couldn't tell if it was directed at all
It does not look like 14 million ought to look;
There is no "Wow!" factor.
A guilty pleasure without the pleasure.
This is proported to be a Bollywood movie musical on stage, but we don't know what a Bollywood opus is, then the show becomes merely bad
The running costs are probably very high.
The show has an advance but not a huge one and needs great reviews and a great commercial to get a run. I wish them well.
