Ah well... i guess I'll throw my two cents in here, too.
I'd rather throw this where people might actually see it, but I don't really have a place to do that.
Okay, this post is going to be very SPOILLERIFFIC so if you've been living under a rock, well... stop reading. I'm fairly certain most of you already know what's coming though.
So yeah... Alicorn Twilight.
I admit to being one of those who are disappointed by this, but I believe my reason are different that what seems to be the mainstream reason. This show HAS always (mostly) been about Twilight, but it didn't always FOCUS on Twilight. Throughout Season 1, Twilight was always there, but it was her friends that pushed the envelope, that pushed the story, and she, being her adorkable self, just kept getting caught in the middle. The stories weren't about mythos or changes or anything... it was about how conflicting personalities and differences of opinions could still be worked around to maintain a stable and heartfelt friendship. What I loved, more than anything else in this series, is the character interaction, and season 1 did it best, which is why it's still my favorite season.
Not that the others haven't had gems, but it seems to me that it's no longer the focus, and with Twilight becoming an Alicorn, the focus is now going in an entirely different direction. Because now Twilight will likely be almost the only one driving the story forward. And I'm sad at that. I'm not angry, or in an uproar... I'm sad.
I'm not sad because this is happening to Twilight. If anything, I was one of those who suspected something like this way back in the beginning. I wrote a story (featured on this site) about Twilight's potential, and what I saw as a possibility, the connection between them and such. I have no qualms about this... but the timing... it's just bad.
I feel like there's a WHOLE lot more that can be explored between these characters still. Heck, we still don't even know the nature of half their relationships. As I explained in the description of one of the pieces on my deviantart my favorite episodes were always the ones that threw two of the characters together and let them bounce off each other. 'Look Before you Sleep' (Rarity and AJ), 'Hurricane Fluttershy' (Flutters and Dash), 'Feeling Pinkie Keen' (Pinkie and Twi)... but there are so many relationships between the girls that we don't understand. How on earth does Rarity relate to Dash or Pinkie? How does Pinkie relate to Fluttershy and Applejack? (Personally, I think an episode based around Flutters and Pinkie could be phenomenal!), Or Twilight and Fluttershy? Twilight and Rarity? Twilight and Rainbow Dash?
With this change, I can't help but see that the series is now moving in a different direction. Sure, Twilight will now have to develop new skills, but the emphasis on 'Friendship' is no longer there. She's essentially 'finished' her friendship studies, and now the focus will turn to her new life and responsibilities. That's not what I came to love about this show. Sure, the backstory and mythos is interesting and all, but this isn't why I fell in love with the show. I fell in love with the show because Friendship is Magic, and these characters were showing little girls how to do it RIGHT.
But after something like this? I don't think there's any way that they can NOT take it in another direction, and to me, any other direction is a step down. THAT is why I'm disappointed in this change, especially in the middle of the show, because the focus is now going to be different.
And that is why i don't want to see it happen.
I accept that it's going to happen, and I'll stick around, and cross my fingers, but my hopes are on an all-time low right now.
