I've recently started to watch the show, but I wouldn't consider myself to the level of being a brony. The animation is simple but still really good(although it can look odd sometimes), and the writing brings back memories of shows I grew up on(funny, good message, etc.). One of my friends is a brony(well, one has stated they're one), and along with him, I saw references to the show on other sites I visit. I decided to give the show after watching the CR Familiar Faces review, and the first episode I saw was the one where Pinkie Pie babysits. When the joke about adultery came up, the first thing I thought was, "okay, this show might not be so bad after all." The jokes/references bring back a lot of memories about Animaniacs. The topics that were brought up in the Familiar Faces review were true, and the show really is entertaining. It's an entertaining show, and anyone who likes animation should give it a chance.
Also, one reason why I was hesitant to watch the show in the first place is because my only experience with My Little Pony prior to this was way back in Summer Camp when I got stuck watching the old show from the 80s.
So it's an entertaining show, but you won't find me doing any fanfic or drawings...that is, if I could draw in the first place.
