I only watched one episode which was the first episode a few months back and I remember the synopsis was like:
A long time ago, two sisters ruled the world and one became evil and got banished to the moon? Then a green unicorn runs to a library ad talks to Spike who is supposed t be a baby dragon but looks like a giant lizard. And then Spike burnt a letter. Then something happened and green unicorn went to Ponyville, now as I write this I suddenly think of Humanville. An then this led to that until the antagonist arrived... then cliffhanger.
My reaction: I'll go do my homework instead.
So my question is why do people get hooked to it? Maybe I need to watch the next episode?
