The only problem is that you hear only about the worst part of the fandom. But ultimately I tend to think that the hate directed at fans of the show is pretty much the same thing as people thinking that all Goths eat children, all Industrial fans are Nazis and all Black Metal fans murder people and burn churches.
I've explained this in prior threads related to this topic, but the hate (even though not totally justifiable in the sense that ALL fans are like that) came due to the sudden explosion in popularity of the show, followed by the quick bandwagon of it. This definitely pissed off plenty of people, as it was essentially EVERYWHERE and the initial community was very "pushy" regarding the show. So in many parts of the internet, this served as a bad first impression, and that ultimately stuck. I can say for sure the community is definitely different now, but a lot of the problems which was present at its beginning is still prevalent today, but I admit they aren't as "out there" as they were prior.
I'm really only focusing on the community over the show, as I think cartoon-wise it's pretty run of the mill and there's not much to discuss about it. It's fine, but that's just really all it is. I just really find it interesting how communities spring up on the internet overnight, form their own general ideas and beliefs, and interact with other communities. I've been around since the show began to get popular, and despite it being rather...odd watching it grow in popularity, it's been interesting nonetheless.
What I imagine will happen with the show, is that the people making it will realize that they can now market the show to an unintended yet profitable audience (The "Brony" community.) They'll then try to shift a lot of attention towards this community and cater the show somewhat to their wants, but will fail in doing so and just piss off their brony audience. Then it'll die out just like pretty much any fandom based on a cartoon or TV show, and everyone will forget about it and get angry at the next "annoying fandom."
