I thought the episode was really good, and frankly better than I was expecting. The casting left me very disappointed, though. I wasn't expecting M*A*S*H*
-level recasting, but damn they could have made some effort to change the character dynamic. Instead we get a diva to replace Mercedes, a season one Quinn kock-off, Puck 2.0 (literally), and New Rachel. I wouldn't be surprised if the New Directions suddenly add a feisty Hispanic girl, a bumbling oaf, and an Asian dance prodigy in the next few episodes.
