I love musicals and I love Trek so I was hoping I would love this episode, but I just didn't, and I think it was mostly because the music was... bad? It wasn't catchy, it wasn't fun, there was not one single legitimate bop during the whole episode. Uhura's last line about an earworm struck me as a sour note because... no. Not a single earworm to be had in the whole thing. I couldn't hum a single song from that episode and I watched it less than an hour ago. The only number that had any spark to it at all was Chapel's number at the lounge, and it was barely a spark.
Even Una's alleged Gilbert and Sullivan riff was barely, barely recognizable as a take on G&S. It was to G&S as a brick spraypainted orange is to a glass of refreshing orange juice. You're gonna do G&S in a musical episode and not do patter? Come on, son.
I just can't get behind this episode, and I was truly prepared to be thrilled. I mean the cast tried hard, but in a musical the music has to be good, and this wasn't.
