The following article contains spoilers for “Subspace Rhapsody.”
At some point in the ‘90s, it became law that all genre shows with a certain flexibility in their premise must do a musical episode. Xena, Ally McBeal, Buffy, Psych, Grey’s Anatomy and Scrubs have all done one, as has Supernatural, Once Upon a Time, 7th Heaven, Supergirl and The Flash. Now, it’s Strange New Worlds’ turn to make its characters spontaneously burst into song as it drops “Subspace Rhapsody” as the penultimate episode of its second season.
