I think the reason a lot of people hate Kennedy, but can't quite put their finger on why, is simple: It's because Iyari Limon did a terrible job with the part. She's a fine actress in her own right--but she just couldn't compare to the calibre of talent that was already on the show. I mean, think about the brilliance of the Kennedy character: tough, smart-alecky, self-centered...totally the opposite of Tara. She's perfect for the next love interest for Wilow. In fact, just imagine how AWESOME the character would have been if, say, Eliza Dushku had played her (instead of Faith). That would have been genius. But as it is, Iyari kind of ruined it. She just didn't have it in her to pull that part off...instead of tough and smart-alecky, she came off as downright annoying. Again, she's talented in her own right--but she was poorly cast here.
