I don't think anyone here is claiming that they want everything to be identical to the books, no-one is deluded enough to think that everything will survive a change of medium. This thread, at least as i judged it and it's how i structured my first reply, is about the differences more from curiosity than trying to hold the show to account. Obviously people are going to have opinions on how well the changes work and whether something is lost or added. For me it's a mixed bag. Some changes like Sansa scene and Cersei+Catelyn add to the show and the characterisation. Others, such as the Brothel scene weaken the show and make it seem puerile rather than adult. What i liked i think i'd like despite the books and same with what i disliked.
Well one thing I liked is I got to see more character interaction that I didn't see in the books. For example the way Jaime and Cersei talked to each other in the beginning. This was good and important because you saw some but not a lot in the first book.
