So here's my analysis of this show. It is not the best cartoon by a longshot, but before you accuse me of spamming or whatnot here me out.
This show is much, much, much better than what a lot of people may think it is. It's a show about semi-anthromorphic ponies interacting in life, and learning what it truely means to be a friend. The plotline is cheesy, but it is on the best end of the cheesy spectrum, meaning that while it can be predictable, the end result is a lesson in friendship, that is actually something useful for dealing with life.
But you know, the only better than the plot, is the characters. I don't care if the plot makes God cry with tears of happiness, if the characters are awful, the whole thing is. And the characters of this show are beyond awesome. While most cartoons (and TV shows and movies and etc.) have characters where the personalities are at least 80% the same, making me believe that they are actually one person split into two beings, many of these characters share maybe 15% of their personalities, making for a good conflict. Actually a plotline that issues a conflict among each other is much more interesting and exciting than a conflict that uses an outside source (example: a villain). And for a bonus, it's really funny for some reason I cannot explain.
So going at the top, the reason why it will never be the best cartoon in my opinion, is that it's competing with so many others. I don't know why, but every single thing I liked from 6-13 including that PBS show Dragon Tales and Pokemon, I must still love today. But if this show was around and I loved it from when I am 8-ish, this would be among be top 3 or 4 favorite cartoons.
So I'm going to say Congrats to The Hub for creating a show that actually is pretty awesome!
