Oftentimes I disagree with the plot of an episode where Rainbow Dash, Fluttershy, Twilight Sparkle, Pinkie Pie or Applejack are "wronged". I may go as far as to side with the person to "blame" (My Litte Pony is huge on blame!) for the episode's purported foibles. This never happens with Rarity who is right about everything and who everyone is so mean to.
I should note that I personally identify as a Twilight so there's no bias here in that respect.
