I've been putting off watching the new MLP episode because, well, I have my doubts to be honest. I'm all for bringing Discord back, that's freaking awesome, but trying to reform the King of Chaos? Really? Now there have been other times MLP tried doing something I wasn't sure about. Heck, that includes the series itself! But they always pull through, I need to learn to remember that. Chalk it up to years of experience with bad cartoons, they've made me a little edgy.
But I'm going to go ahead and watch it in a few minutes, as soon as my muses release me from my current writing frenzy.
EDIT: Watched it, and naturally it was only about half as corny as I thought it would be. I still think King Sombra's going to come back, and that's why Princess Celestia was so bent on getting Discords magic on the good guys side. At the very least it obviously has something to do with that book she and Luna had at the end of the season 3 premier.
