No, I totally agree. Kitty read more like Buffy than Kitty and while there were plenty of good quips, it never felt like the X-men to me. I've always been particularly bugged by his take on Kitty, which basically seemed to be taking her back to the maturity level he remembered when he was reading the books as a teen but adding sex so he could effectively make love to his favourite character through proxy. It felt rather creepy to me in that respect and it bugged me that Warren Ellis very effectively made Kitty an adult with a sex life whereas Whedon ignored all her maturity growth and made her a teen with a sex life. The "tee hee" moment during the first sex scene made me cringe. In that, it felt like he was writing a sub-par Buffy rather than a well-developed Kitty.
