It was enjoyable and quite epicHowever, my taste for the best ending would combine the dark vibe from The Crystal Empire and the promise to future from Mystery Magical Cure. Oh, and I still have a big problem with Twilight's decision to sell the destiny of thousands for few of her friends. This would make sense ONLY if she knew that it would lead her to her key AND if she knew that the box would contain a power that can match Tirek at that point. Which she certainly couldn't know.So the lesson from that episode feels utterly wrong. Just like lesson for Rarity in Canterlot - she was telling lies all the time and THAT lie issue was never solved there. The only lesson was "don't be ashamed of your friends". No "lying is bad". :/
