I know this is late, but Hasbro has a spinoff called Pony Life. It's essentially the Teen Titans Go of MLP. There are some videos on the Official MLP YouTube Channel. My Little Pony Official - YouTube
Honestly, I thought the same thing. Though surprisingly it wasn't horrible. If anything, most of Mane 6 are themselves, except Rarity to a degree. Celestia is full of energy and rather fun~ Basically a bit like the total drama host guy, but with less of the *squee!*-ish personality. Eh. Also we need to keep in mind this is selling toys. Hasbro a toy company first and a animation company second.
