I don't see the problem with the Sam situation. Ya it's new but I doesn't change anything. Everything this is supposed to happen can still happen. Dany's storyline was useless and boring the book too. Unless you happen to be referring to the prophesies, which I am ok with them changing. Prophesies. except in Macbeth situations (Cercei) , serve no purpose plotwise, and destroy suspense. Lastly, I don't see any change in Robb's character. If you think Robb slept with Jeyne only because he we grief stricken and not becuase he was teenage boy away from his mother and alone with an attractive girl then you have some thick rose colored glasses on.
