Well, this is it everyone(pony), the end of season three. So, what's my opinion on the season finale, the big event that has everyone(pony) up in arms(hooves)? I can sum up my feelings for the episode in one word:
Eh...
Not as spectacular as I was hoping. I didn't even expect much to begin with. One could argue that this episode was a huge step for Twilight's character, perhaps the biggest step she's taken to date. While that may be true, it's only because said character development was simply a culmination of all of her experiences over the past three years. This really should have been a two-parter; the episode felt very compacted, from the whole cutie mark debacle to Twilight's ascension to her coronation. The whole alicorn business should have been allowed more time to be expanded upon, but I'll get back to this point later.
I've said in the past that I was never really a fan of the show's music; not that I hate it, I'm just indifferent to it. And this episode was basically Friendship is Magic: The Musical. There was, what, five, maybe six songs? All pretty short and sweet and used primarily as a time lapse tool to condense the episode's events into one half hour, but I found myself zoning out a fair bit during those sequences.
But let's get down to the nitty-gritty here. What do I think of Twilight becoming an alicorn? As I've mentioned before, I'm not exactly a fan. The change just seems too drastic in my eyes. While the show's creators are assuring us that the change isn't going to affect the show or Twilight's role in the show too strongly, for someone like myself (ie; a fan-fiction writer) it can kinda throw a wrench into one's plans, but that's just a personal quip. I still think the change is a tad extreme though, even if the actual transformation sequence was pretty damn cool.
But let's backstep a little to where I said it should have been a two-parter. Let's look at something that show writer Meghan McCarthy said on Twitter:

The implication here being that the season four premiere will be a two-part continuation of sorts of the season three finale, and, if I had to guess, may address the quibbles I brought up earlier, namely not exploring the alicorn thing enough and showing us how Twilight adjusts to her new form and social status.
This information has given me a good idea of what exactly this episode is supposed to be: Hasbro doing what they do best, advertising. The reason we have to wait for the conclusion to this story arc is so Hasbro can give fans a chance to raid store shelves for all of their alicorn Twilight merchandise, nothing more, nothing less. Honestly, it just felt like one, twenty-minute commercial.
So, I guess I'm just going to have to stew in my own displeasure for the next several months to see where this all goes. If Twilight does ultimately remain an alicorn permanently, I'm sure I'll get over it eventually. But, hey, on the bright side, season four is confirmed to have a full twenty-six episodes as opposed to this season's thirteen. That, coupled with the apparent reasoning for such a short season being a shorter time between seasons, will make the wait a little more bearable.
So that's my two cents. No screen-grabs this time cuz wall o'text. Maybe if I feel like it later, but not now. So, what's your opinion?
