Quote memaa7: IMO, Cynthia played Kelly the way her character was written...we were NOT supposed to like her! Now that Cady is playing this role the character of Kelly is changing, NOT because of the actress, but because the role of Kelly is changing, so that the audience likes her with Jack!
I tend to agree with you. The original Kelly was considered as the hit and run driver for a time. We weren't intended to like her. They started to soften her up but since she left the show anyway they have more of an excuse to lighten her up.
