Saw it and loved it. They did an amazing job translating such a vast fantasy story to the small screen. It looked epic.
The changes they made were minimal and mainly to cover for the fact that they could not do characters internal monologues which are a huge part of the books. There was more nudity and sex than I remember in the books, but they were setting up the world and showing that this is not Lord of the Rings. Some people call it The Sopranos with Swords. I see it more like James Ellroy Meets King Arthur. Anyway, it was an excellent start. I’ll be interested to see how it’s received.
