It's interesting that is for sure. I think I just might go and buy the first book at least. Just because I want to know more.
I think they have reduced the dire-wolf bit mainly because perhaps it is too fantasy for general viewing? They are trying to do dark and gritty and wolves jumping about the place killing slews of people may just be beyond the standard sky viewers comprehension . . . . .
For me Tyrion is by far the most interesting character. In a way it reflects my line of work. Instead of just being a character you think you should hate and perhaps do dislike to begin with, not only is their depth, there is explanation. He doesn't really want power, he just knows that by using power he gets respect. So it almost does make you feel guilty that you may have judged him early on.
As for the bit in the tent - I thought that the night bit hadn't arrived yet? Or was the whole horse slaughter and baby bump trauma meant to have happened during the night?
