Musically, this song works. This is what the other songs on the album are aiming for but miss. Here it hits the mark.
As for the video, it starts out nice and cozy, high society love, castles, white horses and all. Then Taylor quickly starts looking insane when her lover is on his way out of there, perhaps because of her jealousy.
Basically, she’s saying she’ll get crazy if she senses you might cross her, whether the intuition fits reality or not.
This video will ensure Taylor Swift’s dating life dries up.
