Let's have a nice little thread to talk about the episodes that we find truly off-putting. These aren't episodes we dislike; these are episodes we hate, and we want the world to know, dangit.
For me, the first episode that always comes to mind is "The Best Night Ever." This episode and its "moral" annoys me on so many levels. What even was it? Never look forward to anything? Don't go to parties? Always stay with your established friends and don't branch out? On a logical level, I understand the idea was "don't overhype anything", but it was executed so questionably. Seeing the Mane6 have their hopes and dreams dashed isn't particularly enjoyable (even if there are funny moments), and them making total jerks of themselves by ruining the gala for everyone isn't fun either. Oh, but don't worry; according to Celestia, that doesn't matter because the gala is always "boring!" Let's all laugh about it! Seriously... what? It's especially jarring since this was a season finale that was (somewhat) built up throughout the season.
Enough about me though. I want to know which episodes upset all of you.
