Not going to be good. Just not. I do see flashes of fun when the Brotherhood are being bad guys. But the Wolvie and X-Men bits just drag. Which is not a good thing when your movie is called Wolverine and the X-Men.
And WTF is up with Ororo's hair?
(And why don't I write about comics more?)
EDIT: And, speaking of hair, I have spent a not-inconsiderable portion of my afternoon trying to find decent pictures of Toshiko from this season of Torchwood. Why? Because Elayna wants her hair. The long bangs, the shoulder-length bob tapering longer up front. I have talked Elayna down from shearing her hair off at the nape of her neck and leaving two hunks of waistlength "bangs" up front. Beloved child, sometimes things that work in anime Do Not Work in Real Life. Tosh-hair is a good compromise.
