Jennifer doesn't seem to have the personality to carry a talk show. I watched one time and she seemed awkward and uncomfortable. I guess she could learn and grow into it.
As for Kelly, I agree that she is a terrible interviewer.
She doesn't shut up and turns the interview into her own experiences and opinions. Everything becomes about her!
(Perhaps she would make a suitable QVC host.)
My favorite daytime show is Drew, but unfortunately ratings are poor. Oh well....she had a better run than many others.
