other way round for me mate.
I've read about half of the first book only, and so far enjoying it. I watched ep.1. I thought they tried to cram too much into it...the episode encompassed almost everything I've read so far. But that's pretty common with pilots...introducing everyone, trying to get all the plots and subplots off the ground. Anyway, I thought the book started slow.
Without spoiling anything, I did think the circumstances of Bran's incident were different enough from the book as to affect the plot somewhat (what he saw was not as scandalous in the book as what he heard...in the show he heard nothing).
I'll watch the next few episodes before passing judgment, but I think it shows some promise. It could still go either way though.
