Oh goodie, we're doing the pile-on-Meghan-McCarthy thing again.
It's not "piling on" to criticize or to try and figure out who did what. I had just been watching a review that focuses on the show from a writing standpoint (very critical but also very positive), and he said that MA Larson was probably the single best writer on the show, but... Magical Mystery Cure.
And then Mitch says that the episode is hard to talk about, because it's not really what he wrote. It's "roughly" what he wrote, but it was changed heavily by Meghan.
Mitch says the end product is messed up, structurally. The climax is in the second act, and the third act is a party. Mitch was criticized for not understanding structure, but Mitch criticizes the structure in the rewrite.
The logic of the cutie mark juggling never made much sense. Starswirl wrote a spell that messes up cutie marks (if you happen to be the Element of Magic and are connected to other ponies through the Elements of Harmony). But he never figured out the antidote to this spell because he never knew nothing bout friendship. Twilight is an expert (thanks to Celestia), so she fixes her friends, but then putting pen to paper teleports her to Celestia, who gifts Twilight with wings as if she just passed a simple friendship test. But in Mitch's version, Twilight lets Pandora out of the box, Celestia says it's impossible to fix this, but Twilight tries anyways, and manages to do the impossible and earns a set of wings. In Mitch's version, Twilight did what Celestia couldn't do, but in Meghan's rewrite, Twilight did what Starswirl (a throwaway gag from one episode) couldn't do.
Twilight getting wings was rushed because it was based on a misunderstanding of Lauren Faust's notes on Twilight's character arc, and another misunderstanding about the show getting cancelled. Mitch speculates that the changes to his script were made because Meghan learned that the show
wasn't being cancelled. But if that's the case, why did Meghan change everything
but the core problem of closing out Twilight's character arc? Just make a musical episode about Pandora's Box that
doesn't end with Twilight flying off into the sunset.
Mitch has been liberated from possibly the worst-written episode on his resume, and entirely new questionable decisions have been attributed to Meghan's leadership. It's silly to ignore these things because you think people are being unfair to Meghan.
