"Fantastic Characters" You mean the myriad of OTHER children's televisioning with pretty much the same character types and personality? (example: If you have ever seen the children's television show, "Clifford the Big Red Dog" then you know of the character Jenna, who is exactly like Rarity, but more bearable because she isn't isn't a main character) "Good Wiriting" Meaning taking pretty much cliche episodes that you see from other cartoons? (But I will concede that while many episodes of the show are cliche and bland, a few episodes are actually interesting) And by "Fandom" do you mean the disrespectful fans who seem to want to insert their oh so beloved ponies into everything including pictures of historical signifigance while saying "Oh look at that brave pony, standing up to tyranny I feel so connected to that historical moment now" and the fans who disagree with all opinion while looking through rosy eyed glasses at their magical show while ignoring all the inherent flaws present? But the animation (for Flash) is really good.
tl:dr Everything is boring and bland but the animation is really good.
