Hard to tell but I think they might have dropped a big bollock by cutting the music budget / deciding there wasn't time for an extensive incidental score.
Plenty of other worries, the big one seems to be, does this really have the heart of GOT? It was so schlocky for long periods, but it got away with it for years. This is more even all round, but it might be totally wasted, another dull, talky CGI fest. The dialogue, budget constraints, maybe it all needs to be WORSE so I trust that they're holding back for good bits.
