Hey, I'm as big of a fan of the vintage line and the comics as the next guy, but so far I've liked what I've seen with possibly one exception; Cover Girl. Not really a fan of either the uniform or the model they picked to play her but we'll see.
As far as the uniforms go, there wasn't really a doubt that they'd put a modern spin on things but, honestly, would you really want to see Gung Ho, for example, in turquoise colored gucciflage? Sorry, but I wouldn't. To goofy.
As long as they keep the heart of the characters I don't really care so much what they dress them in. That's one of the things I liked about the X-Men films is that the characters, to me at least, seemed mostly true to their comic background just in new uniforms.
Oh, and I love Storm Shadow's outfit. I was wondering how they were going to pull that costume off without having a guy running around in the vintage-style, full-on ninja outfit.
