Nooooooo the forum just ate my post! T_T Time to rewrite a shorter version... Anyway, some of my own random thoughts about the show's appeal, trying to avoid repeating what others have said: For furries, I suspect the talking horses get the show one or two extra points, but I think its popularity among that group probably has more to do with furries being more *embedded* in online culture in general than most people are. So they're more or less in the right spot to be exposed and potentially become fans. (Oh hey, NOW I get the autosave message.) As for the general popularity of the show itself, well, it *is* usually a bit better than most other cartoons. (Though I'll admit the quality has become more variable since Lauren Faust left the team.) But more than the quality itself, the wide appeal probably has more to do with it being surprisingly age- and gender-neutral. Kids can understand it without adult audiences feeling like it's insulting their intelligence (most of the time). There are also some references and jokes that only adults will get, and I can think of at least one joke that would be WILDLY inappropriate for kids if it didn't just fly over their heads. For the gender neutral thing, the show pretty much avoids stereotypes about what characters should act like based on their gender. I mean, seriously, they could have animated and cast the show with all the characters gender-flipped but using the exact same script and the only noticeable thing would be that male Rarity is really flamingly metrosexual. (Which I think speaks to some other hangups our society has about gender roles, but yeah.) But another aspect that I think makes a HUGE contribution, is the sort of world and lore it has. Basically, it's the kind of world where it's easy to create your own characters and stories without just making Mary Sues or changing the lore until the result is barely related at all to the original source. There's a ridiculous amount of room to expand while still being recognizable as MLP. Honestly, I think this is probably the biggest catalyst behind the fandom being able to expand so much. THOUGH I WILL ADMIT I may be somewhat biased here, as I actually tend to enjoy all the fan-created insanity more than the show itself. And of course this aspect means there's plenty of fertile soil for insanity to grow. P.S. I regret to inform you that yes, friendship is literally magic in the FiM universe. Fortunately the show focuses more on the metaphorical magic of friendship, but you're probably still gonna gag at a couple episodes.
