Apparently the season 3 finale was divisive, or something. Who here has seen it, and what did you think? (No, not just "It was terrible just like every other episode.")
Myself, I thought the episode itself was good, except for the coronation scene. That one was kind of silly...
As for the development itself Twilight becoming an alicorn, I am neutral. My reaction was basically, "Oh. That's interesting."
