The thing I hated most about Rainbow Rocks was Applejack. She was a selfish jerk. That movie is why I hate human Applejack, despite liking pony Applejack. That movie is why I cannot consider the human six and the mane six the same characters, at all. Pony Applejack doesn't look down on others and think she's better than them. Human Applejack can't. In fact, human Applejack thinks she knows everything.
I think Friendship Games was much better.
