Love the show, haven't read the books.I also haven't read the books even though I was tempted to buy them and read them, I just thought it would be better for my wallet if I didn't. I also love Henry and since I saw the first season of the Tudors it just reminds me that he plays King Henry III's son. I also agree with you on the Mike character because he also doesn't appeal to me either.
I flat-out adore Henry (and it tickles my funnybone that he's Henry Fitzroy). I don't like Mike though. He's just doesn't appeal to me.
