I enjoyed it a lot. The opening with A Chorus Line was an unexpected, absolute riot. I went in with the expectation that it was a concert (in the popular sense--not a concert presentation nor a revue), so color me surprised they actually performed choreographed numbers.
I thought it was great they were showcasing new artists, many of whom were also the gifted backup singers. I was disappointed they didn't have real special guests, but I got over it. I get that it's a head-scratcher, since NYCC didn't provide any context to the show before or during tonight. It's no wonder you all had different expectations from each other.
After reading the playbill, I was mentally prepared for a "showcase". I did feel explanations between songs were missing though.
Can't say I understood the song selection; I just figured they were songs that meant something to somebody... either to Jonathan, Sutton, Jean, or other people involved with tonight's performance. Like "Left Behind" because of Jonathan and "Ring of Keys" because of Jean.
I didn't recognize most of the songs anyway, both musical and pop, so I guess the randomness was all the same to me. People laughed or cheered when songs came on like, "Forget About the Boy", Beyonce's "Love on Top"... but they were the first time I've heard these songs.
Maybe I'm more forgiving because I love Groff, had zero expectations, and sat in the cheap seats, anyway! And knowing how much Groff idolizes Sutton, I just thought how fantastic it must be for him to be working with her! So his amateur tapping/dancing made total sense to me because of that. *shrug* Things sort of just worked itself out in my head, so none of it bothered me and I enjoyed myself.
