I've seen bits and pieces of the show now and then, but not at all for about ten years. It seemed ok, I like her well enough and she doesn't seem evil or anything.
But really, I couldn't care less about Oprah or any other celebrity. I find the whole celeb "industry", if I can call it that, a colossal bore. An entertainer, can entertain me in a show, or a movie, or a concert, or a video, or whatever, but when their job is done, I have no interest in their opinions or their personal life.
This is my opinion and I don't care if you enjoy Oprah everyday. No judgement from me.
