The first two episodes look spectacular, I think, especially when seen on the big screen at CAA. Cinematic quality. (I have a new 55 inch TV set being installed this week, and now I'm afraid that it's too small) These were the first complete episodes I've seen, and I loved them. Yes, there are changes from the books, and of course there are things missing -- lines of dialogue, bits of business, scenes -- but without twice or thrice the running time, there was no way to get EVERYTHING in. The story is there, that's the important thing. Fans who know the books inside and out may miss certain things, sure, but the vast majority of viewers, those who have never read the novels, should do just fine.
My hat is off to David and Dan and the team they put together. They've done an amazing job.
Oh, and HBO has released a new trailer. Herewith, "Poison."
