They are trying to fix what isn’t broken. I really like Greta myself. She really does an excellent job. I genuinely like her.
Greta is by far the best host they have. She knows how to do an interview without talking over the guest. Yet, if a guest is not answering the question she interrupts at the appropriate time and tries to prod an answer out of them. Unlike Hannity, Greta actually hears the guests answer and responds to it. Hannity just seems to respond with whatever talking point he has on his mind. I like him, but he is not a gifted interviewer.
