Honestly? I am ^^.
The episode not only gave me a redemption arc to Tiara (something I was waiting for a while), but the way the obtain their cutie marks is unaspected to say the least. It's not just the fact that they helped a pony who they used do deride in the pat (not that I balme the for ), but they finally stopped about trying forcing a cutie mark on themselves, learning that helping others is more important (sure, it's a bit silly the fact that, right whe, they say "who care about cutie marks anymore", bang cutie marks for yah xDD. Also, was it really needed to make that scene similar to Twilight's alicornification?). Only sad thing is that, now that Diamond Tiara is good, the show seems uninterested about her anymore; I mean come on, you can like make an episode about her and her mommy's issues, perhaps giving some reason on why Spoiled Rich's like that, you know...
