I don't know... It didn't feel special to me, while I hoped it would.
First of, I really loved Spike in this episode, but it came out of nowhere. Never have we seen Spike felt left out. This could have been built on a bit better imo.
Then, I really liked the stuff between Luna and Tia, and the plan of Spike and Luna. That was very special to see and very well executed.
At last, the plan of Rarity was not really convincing to begin with. I liked she took charge, but I would've liked to see them coming up with a plan themselfs, not just switch the old plan...
Overall, it was enjoyable, but not very special...
