My thoughts, after my initial viewing and after letting 8 hours pass. I originally intended to make this short and simple. Then I got carried away:
The writers created Twilicorn without breaking the world or the character. I would have liked to see more worldbuilding RE alicorns (it left several questions hanging), but it did the job. We didn't get to see much of the "fallout" from Twilight's ascension (i.e., "now what?"), so it'll be important to see how that's handled in Season 4.
Speaking of Season 4; if Celestia's words are anything to go by, there are going to be some major changes, probably both in-universe and in terms of the writing and storylines. How exactly Season 4 will differ from the first 3 is anyone's guess.
Cerebus Syndrome is certainly on my mind, but I could be completely wrong. Regardless, they don't seem to be slapping wings on Twilight, changing nothing else, and calling it a day. Even bearing in mind fears of shark-jumping, I'd say this is a good thing. Making a major change in Twilight like this and then going back to business-as-usual would be poor form, and after 2.5 seasons of the same basic format, shaking things up is probably a good idea. I'm really eager to see exactly where they go with this.
And the term "alicorn" is canon now (not just as the name of the Amulet). So that's just awesome.
The ep itself was...good, but definitely flawed. Good material, as usual; songs (Celestia Sings!), jokes (Pinkie Spit-take!), character interaction, fan shoutouts (
Derpy!!!) etc., were all well-done, and there was a lot of it. As for the ascent/coronation itself, I don't think I can begin to complain about that section.
But the way that material was organized detracted from the ep. Mainly because yes, the pacing definitely felt rushed, and the Cutie Mark-switching section felt rather tacked-on as a result. I'd really have liked to see Twilight's final test be something more weighty and taxing (e.g., The Royal Wedding or The Return of Harmony), since passing it is such a Big Deal, and the "payoff" is so significant. The Cutie Mark-switching story was good, but run-of-the-mill as the show's
plots storylines go, and this cheapened the ascent and coronation's emotional impact.
Honestly, though, I'm not sure there was a way around that; they essentially had 11 minutes to work with. Many people have already said it, and many more will say it; this would have been
way better as a two-parter (and with the story's conflict expanded to match). Sadly, that's not for the writers to decide. It's especially disheartening because the writers, animators,
V As, and composers clearly brought their A-Games, both for us and for the kids.
I'm tempted to call it a "noble failure", but the material that's in the ep is too good for that descriptor. Still, it's hard to watch it without seeing the missed potential. I've felt like the show was harmed by its time constraints before (again, The Royal Wedding and The Return of Harmony spring to mind), but never as severely as this.
At the end of the day, though, the ep was entertaining, if flawed, and Twilight's coronation seems to have left the spirit and world of the show intact. We'll have to wait for Season 4 to know for certain. The ep itself may represent a stumble, but as far as I'm concerned, we can put away the shark tank and waterskis for now.
