it depends on your way of thinking. If you just watch a show without thinking about a different meaning, this show for example, then it will just seem like some stupid kids show. But for me this show has different meanings behind it and shows some problems in real life. Others like this show because its cute, the songs are catchy, and its interesting..
cause its cute and random
I'm not sure why teenagers find it entertaining, but I'm not surprised that talking little horses appeal to children.
And then there's the bronies...
Lol, I think it's oddly hilarious because of its stupidity. X)
