Well, they could have put more of an emphasis on Davos, who will become one of the more important characters later. To be honest, I thought the episode was bad, but that's mainly because I thought that of the first series as well and because I don't really like the hype this show has been getting. The books are about a 1000 times better. I think if they would have spread out the story a bit more evenly, like say 15-20 episode a book instead of 10 there could be a lot more explaining and stuff. Very often it appears stuff just 'happens' out of nowhere and you have to guess what the hell is going on. It helps that I've read the books but I can't imagine anyone who hasn't done that knowing who the hell Hodor, Osha, Asha, Craster, Cressen, the Bloodriders etc. is.
