Man, this episode is so back and forth for me. On one hand, it was a comedy of errors in which a character makes a fool of himself for the sake of humor. I tend not to like those, at least not ones that are so on the cuff about it. Often, this sequence is caused by a misunderstanding or overreaction, and could easily be resolved by five minutes of dialogue... or ten seconds, as this episode proves. On the other hand, there were a lot of great moments and expressions that were absolutely funny as hell. The entire realm of chaos, as well as the little visual gags they always put around Discord, were welcome as always.
Back with the first hand, The generic Rastafarian character tends to be super over the top and hard to dig. And oh lord when she started "singing," what even was that? Kickin' it with the second hand again, she had some great moments, and we had a few wonderful scenes with other characters both leading up to and at the gala.
All in all this episode was okay, mainly for the reason that a lot of it could have been resolved, as I said, by a very brief conversation and explanation. Fluttershy has been very insightful with her other friends as to what they need and how they work. For her to be so absent with Discord felt comparatively weak. Meanwhile Celestia... crazy old girl, hoping weird shit goes down. Never change, Princess.
