I really didn't enjoy Kinky Boots. I found the show to be an efficient crowd-pleaser but I didn't get the whole "heart" thing that the marketing - and posters here - were promoting. I found the choreography weak, the score unmemorable, the accents atrocious - the worst of any professional show I've seen - and the performances weak.
One positive. It wasn't too loud, which is a complaint I have about some of the British imports, especially Matilda.
Some people around me left at halftime. I couldn't, as I knew people in the show, but wished I could join them.
Having said all that, the audience, for the most part, were having a great time. I didn't but, hey, it's still running so what do I know?
