I saw this earlier this week. I found it very enjoyable, thought the cast was very strong (not a big LO Jr. fan, but I though he was really excellent), but I did not love it.
My issue with this production is probably not fair: I would much rather have seen Purlie. Repeatedly though the play, which I had never seen before, I found myself reflecting on how terrific a job the book writer for Purlie had done in adapting the play into a musical. Then I found myself thinking how much I would love to hear song X instead of dialogue.
After the performance, there was an audience talkback. I actually asked if they had ever considered reviving Purlie, given the lead. Someone said that the estate would only let them do PV and Ossie Davis's daughter then explained that they wanted to go back to the work her father wrote. I did not say anything, but I did think to myself that Purlie would not exist if Ossie Davis had not written PV. PV is a very good play, but I would have enjoyed Purlie more.
Refecting on it, I think Purlie has always been an underappreciated musical; for example, the always mediocre at heart musical Applause won best musical and best score, which was a joke. The show was a hit because Lauren Bacall was terrific as Margo and there were a lot of good things in it, but the whole definitely did not equal the sum of its parts.
