Musical episodes have worked in live action episodes. Like everybody said Whedon pulled off the musical episode of Buffy and other shows since then have had great musical episodes. Plus I don't think a musical episode in a show with time travel, super speed, a shark man, and a telepathic gorilla is dumb. If done properly with Harris as MM and Whedon directing then I don't see how this can fail unless the firefighters defeat MM this time as well.
