Interesting topic, and I too have to think about it. I've seen a discussion like this years ago on Nightscrawlers forum and I can tell you that opinion often seemed to go with whether or not the person posting the opinion was male or female. I tend to lean towards liking Kurt as a sexy swashbuckler, and Cockrum often drew him as such rather than quite so animalistic although he still had the crouch (First Nightcrawler solo for example.)
Anyone notice something crucial that's missing from the bottom picture?
I haven't bought any books since my initial disappointment with Gold. I'll have to check out Red. I hope Kurt gets some major panel time and development. It's looooong overdue.
