Just an opposing force to my other negative post.

A lot of people come to love MLP:FiM because of memes, but people outgrow memes, and no brony has outgrown MLP. These guys really do appreciate the show for its writing, stories, etc. Also a major factor is the fact that bronies are tearing down a sociological barrier between the sexes that could not occur until MLP was cool enough to do it. Because FiM does not wallow in girly cliches, but actually develops characters and creates real emotion, bronies are able to declare that this show is worth watching, despite its predecessors' reputations. Just as girls have gradually been increasingly inclined toward more realistically masculine things than the original MLPs, so guys are realizing that sometimes, its okay to be a friend, and not JUST a bro. That so many dudes support it so vivaciously is because they are a cultural movement that want's to make its voice heard, not just people saying they like it, ironically, when they really don't.

No, it's not a bandwagon thing, or even that we think it makes us "cool(Even though we are the most awesome ;])" We watch it because the show has good writing; realistic, three-dimensional, funny and relatable characters; good plots and morals that a lot of adults need to learn, good music, and a good animation style.

Now, if you'll notice, these are all subjective things. In the world of art, there's no ultimate authority on whether something is good or bad. As good entertainment is subjective, sometimes someone's going to like a show, a book, a song, or whatever, sometimes someone's going to like something and you'll just never understand why they like it so much.
