To clarify, this topic is not "What got you into MLP?" No, the question of this topic is "What made you keep watching it after you started it?"
As for me, I honestly don't know how to explain it. Something about the show just...attracted me and appealed to me and made me enjoy it and wanna keep watching after I started. It's like there's something in my psyche that I can't explain that the show is somehow like a magnet to or something.
