I'm thinking it has to do with the new season. The 1st season for ones who hadn't read the book was a wholly original animal. The 2nd season is simply a continuation of last. So all the shocks of last season have matured now.This thread seems to be much more critical of this season so far than the first one.
Gotta say I'm not seeing the drop in quality some people are claiming.
I'm still amazed at all they crammed into the first season. Now it's starting to feel like business as usual. It's still a great show, but part of what made it great is missing this season. It's lacking the normalcy that Ned provided.
I like how they split up his legacy between Jon & Robb (& probably Arya)
