Every day I find something to make me estrange myself from the MLP fandom a little more... :P
Princess Diaries 2 was mainly poked at for being woefully unfunny and unsubtle to the worst degree in that video. It also noted how the main character alternates between materialistic excess and pandering, and seemingly being independent and responsible before it's dropped into pandering for a "joke."
I think I'll take the advice on balancing from the end of the video, and start reading Jane Austen novels while watching The Expendables as well. :P
