Okay. In regards to the Sansa/Shae scene, let me lay this all out for you, bit by bit. First off, they skipped right past the parts where Shae was kept in the kitchens and with Lollys, because those would have required them to cast more characters. In a series based on books with such an incredibly huge amount of characters, they need to boil it down to those necessary to move the plot forward while still maintaining as much faithfulness to the books as possible. This was also their reasoning for cutting out Jacelyn Bywater and just using Bronn. Also, in the show, aside from her expression and responses when interacting with Joffrey, we really haven't gotten to see how her position has affected her personally. We don't get to read her stream of consciousness, we don't get to see her thoughts, and we haven't seen her cry into the pillow at night. You may know that happens from reading the books, but I feel the books have clouded your perceptions of the show--someone who hasn't read them won't have seen the despair she's going through. Yes, they could have written a scene in which she crawls into bed one night and cries herself to sleep. But that would have been airtime with only a single purpose--characterizing Sansa. The scene as it is introduces Shae's new role as handmaiden, shows how ludicrously unprepared she is, which in turn gives logical basis for Sansa to be suspicious. And furthermore, it gives us that characterization of Sansa being overwhelmed and barely able to keep it together in this awful situation she's in. I don't think it makes her look bitchy at all--it makes her look human. If she didn't break down, didn't finally lose her composure once that last straw broke the camel's back (and in a safe environment for her to do so, no less), she would make much less sense as a character. Beyond this, the show is getting a much richer portrayal of Shae than the books. In the books, you only saw her from Tyrion's perspective, this sweet little sex kitten, precious beyond anything and maybe-possibly returning his feelings of affection. In this scene, we get to see her interacting with someone else, which highlights how she's just sort of entitled and bitchy. It brings to life the "I didn't want to do real people work, so I ran off and started selling my body" sort of mentality she has. So there. In my opinion, it was a worthwhile scene. And people on these forums actively look for things to complain about in both the books and the show.
