What a weird episode. I kind of loved it. But I also kinda feel that Star Treks somehow jumped the shark. Conflicted I am.
If Star Trek survived the space hippies, Uhura's fan dance, a couple of lackluster TNG movies, plenty of wacky Ferengi comedies and holodeck eps, and any number of oddball, offbeat episodes (of varying degrees of quality), it can survive a musical ep.
Trek is nothing if not resilient.
