This was, to me, a perfect episode. There was absolutely nothing that happened that wasn't hilarious, adorable, or interesting. It had world-building, lots of character moments and facial expressions (including an *amazing* scene-stealing deadpan from Rarity), and was an extremely good/important 'lesson' episode much like Maud Pie's theme of different ways of emotional expression are still valid.
On a personal joy note, since I'm an unabashed huge Twilight fan, it made me giddy to see both flying buddy and study buddy sessions with Dashie and Twilight. It also had what is easily my favorite random Pinkie scene in the whole show so far. The fact that it was so horrifically, distinctly 90s just had me in stitches.
