I was optimistic for the opener but now i'm kinda worried.
I had a feeling they would go down the "OP Flurry" route but i didn't think it was going to be this bad. She seems like she's gonna be a Deus Ex Machina, and hinting that she is the main series antagonist raises some red flags, because, come on, NOBODY cares to see an alicorn baby as the main villain of Season 6. I'm more excited for the Starlight Glimmer/Sunburst plot than Flurry Face.
I hope her powers have to be taken away by then end of the premier.
But, i'll judge it when i see it, and i'll stick with the show until it completely jumps the shark.
