K so you like it mostly because of who made it? I can understand that
Any other reasons? (not trying to be bitchy I'm just wonderin from others lol)
Animation, The happyniess it gives me, all the characters are very well developed and likeable rather than girly muck. I also like some of the songs aswell, normally I hate stuff sung in TV shows but MLP:FiM pulled it off very well.
I dunno, but if you really wanna see why alot of people like it Season 2 Episode 3 would be the best answer since alot of Bronies loved it.
