I agree that there are the same type of characters but they don't have the connection that viewers had built with characters like Tony, Palmer, Michelle, Curtis and even Chase. I mean, I could see them arguably saying Palmer, Tony, and Michelle needed to go because they were there for long, but Chase was there for no time it seems and Curtis... why was that necessary at all? If they have any hopes of continuing the series without Jack Bauer (as kiefer sutherland indicates he wants to do) they would have to groom another character that the people like and think is bad ass, as far as that goes, how long can they string Jack Bauer along as a sort of Brett Favre of the anti-terrorist world?
