I'm not sure what the obsession about ponies is. I don't want to seem critical, and we have a club for this at my school, but what is so great about a cartoon made for children?
Cartoons, any cartoon will bring a little color into your life.
Plus there is that wonderful concept of cartoon physics, which we haven't seen a quite a while untill FiM came along.
Do you have any idea how many great cartoons there are in the world?
Plus its not really made for just children.
And even if it was, as a person who just likes cartoons and animated stuff in general it doesn't matter what audience it was intended for, I mean I've watched far worse things, Winx Club anyone?
Now that is a show meant for *** little toddlers. *shudders* Its a horrible, horrible show that kills your brain cells. It does have a funny abridged series though.
EDIT: You can try and check out the cartoon "Ruby Gloom", certainly meant for little kids but its just so adorably made that anyone can enjoy it.
