You with your Thing for redheads? ;) I don't think I was esp. struck by her in the earlier movies (was all about Rogue/Anna Paquin for me) but Eric seemed almost to be implying that she was unattractive in the previous movies -- and partly this is just him, who's always being (without malicious intent) a jerk about something or other.

I know basically nothing about Kitty Pryde, but I think Joss just has a Thing for tiny girls kicking ass.
