I liked the Kingsglaive movie.
Obviously it's not for everyone, since if you hate FF15 I don't think you'll be that hyped for it, but I liked the parts where stuff actually happened. There was at least one point where I guess I'd agree was a total mistake and they should've used someone else for that, but that would probably have ended badly by the end anyway even if it hadn't gone that way.
Basically, the action sequences are fairly intense, they at least try to give characters their do, even Lunafreya does something cool [despite being the least powerful cast member overall and she's so resigned to her fate that it gets annoying even when you get what she's trying to do] and basically everything to do with General Glauca in the last act was awesome.
Would watch again, recommend to my friends, and hope people like it.
