Um, MLP:FiM is, too me, a good cartoon. It's more, yes, like it actually has characters that I can relate too, unlike most cartoons which seem to be just gags. I like most of the fanbase of this show, aswell. It's very.. um, creative? Yeah. Most of the fan art (music, pics, stories, anything) seems to be a of good quality.
That and the animation style of the show itself is some of the best, IMO, since The Ren & Stimpy Show.
