Canterlot Boutique is not a bad episode.

Ok everypony, we have rights to state what we hate and like,- I'd better shut up and continue.
It's a great episode, it has 2 songs, it has a rarity who is the main pony, rarity is a combination of applejack twilight, and fluttershy in that one.
YES:

• she charmed the mail-pony into making her another delivery(their ponies, and don't have high-tech things like us humans, plus, there is only one mail-pony)
• She made 400+ dresses and didn't sleep, better than twilight's record.
• Ummm, i rate it 100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000%
