I enjoyed it, but in no way would I describe it as a 'perfect musical'. To me it was like cotton candy, fun while it lasted, but when it was gone, there was no lingering effect. Walking to dinner afterward I couldn't recall one tune. I did get the feeling that I was being beaten over the head for 2 1/2 hours, and the number I liked the best, 'I'm Not My Father's Son', actually occurred when the show slowed down and caught its breath for a minute.
FWIW, everybody I've recommended the show to has enjoyed it, but nobody I know thought the score was memorable enough to buy the CD (we're old, we still buy CDs)
For me, a few of the musicals I consider 'perfect' are South Pacific, A Chorus Line, and The Most Happy Fella. I haven't seen Hamilton, but, IMHO, Kinky Boots is certainly not of that caliber.
