I thought it was pretty good, I don't know what the story is, but I'm not really looking for it, I'm happy enough just seeing all my old friends again. Chie's hat magic was unespected and very cool, and Haruka's badassness was once again top notch. She was still fighting AND talking smack after being sliced in half, lasered through the torso and turning to stone.
In other news...WTF, Ghost of Shinso can turn things into stone?!?!
