I don't think the musical episode was either that special or that awful, which is kind of surprising because with the show taking a chance like that, you'd expect it to fall into one of those extremes. I mean some people really loved it, some really hated it, but my own impression was more "that was okay". The Beecher/Schillinger duet is MADE OF AWESOME OMG! But other than that, I didn't get particularly wowed. Hahah it was worth making for that routine alone though :P But it wasn't exactly best episode ever type stuff like the Buffy musical was
