I didn't really like it. I'm sorry. It was far too rushed, and felt a bit... off. The animation seemed of lower quality than usual in places, and some of the voice acting as well. The premise was hard to swallow anyway, and the sudden shift in Discord's attitude fell completely flat for me. It seemed like there were many ideas developing as to how Discord would use the situation to separate Fluttershy from the others, and yet they kept screeching to a halt and being replaced with another one.
The only bit I really liked was the revelation as to why Discord was eating paper. That was the only time I laughed.
