While it doesn't have X-23 in it(which it absolutely shouldn't anyway!), this Motion Picture directed by Mathew Vaughn seems to be shaping up well.
I may be in the minority here, but I'm digging the costumes, and pictures released so far. The entire film seems to be perfectly capturing the Fox Universe of X-Men's origin. Yes, I said FOX universe. This isn't 616 Marvel X-Men. It's maintaining continuity to the X-Men movies from Fox.
This means, no Scott Summers as he was recruited post vietnam, and no Jean Grey as she was recruited in what seems like the 80s. This film is going to take place from 1942-1962 and seems to fit perfectly alongside that.
Now here's hoping the recent damage control that Vaughn has been playing, as well as Singer isn't a sign of things to come. I hope they continue to just make the best picture they can, and ignore the screams of rabid fanboys who you can never please anyway.
A note to filmmakers, don't bow to the whims of fans who don't understand what you're making since they've yet to see it anyway. Just make what you envision, and see where it lands. It's not like there's any comic precedent for this universe, so just keep it in synch with the others and you're all good for any story you've got planned. So keep up the good work, and keep on working. Don't worry about the rabid fanbase who probably never intended to pay to see it anyway. Mind you, this doesn't apply to Superman. Superman is a whole host of different arguments that makes me glad I'm only focusing on Marvel here.
Besides, it's got Kevin Bacon. How could it go wrong?
Personally, I'm still holding out hope that after this, they decide to do an X-23 feature. A feature that could perfectly tie into X4 in forward thinking stories. Though from the sounds of things about XFC, we may be getting a sequel to it at some point too. Much like how there's room for Wolverine movies before he joins the X-Men; First Class seems to be the setup, with the full on caught up connection in a later on feature or features.
