And can someone explain to me why MLP is so popular with not just adults but both genders? I don't mean it in a hateful way but isn't it meant as a commercial-cartoon for a product? From my memory those usually suck. What makes it different from, umm, for example Dora?
Lauren Faust wrote the show to be one that though it was for children, parents wouldn't want to slam their head though the kitchen cabinet while watching with them; in other words, its not just "let's do something to entertain your young simple minds!" Characters have real personality & development. The voicing is well done & the VAs work so great off each other that at times its easy to forget they're reading lines rather than just talking. The plots are well thought out (usually). & most important of all, even though the mane 6 are all girls, very few of them fall into the girly stereotypes of the past generations of MLP. Then the fan contribution is a big part. Some of the fan works inspired by the show are amazing & have a lot of thought put into it, or at least dedication (check out pun pony on tumblr who has been doing 1 submission a day for over 2 years now. Or if you're into Doctor Who, check Discord Whooves [warning, NSFW early on] & the Torchwood & Master blogs that for along with it).
The downside is the fan base can be very dramatic.
