Yeah, that whole scene was pretty dumb, particularly since they didn't bother explaining how they managed to penetrate what I would assume to be a decently guarded royal palace. The assumption that one can just dress up as a random palace redshirt and enter unchallenged is really hard to swallow.
I had to fast forward skip all the Theon torture parts. How anyone can want to watch that I don't know.
Since the marriage was never consummated she isn't technically married to Tyrion.
Yeah, I think the main difference is that we like Sansa and don't like Theon although people were mad about Cerscei having not quite consensual sex last year and she certainly deserves to have bad things happen to her.
Very few people know what Ramsay has done. The Sparrows have seized power very briefly, this is a matter of a few days or weeks, and with the kingsguard and the city watch basically gutted at this point, who's to stop them? Cersei was very well protected for a long time, so no one could hurt her.
Mostly they've combined characters to an absolutely criminal level, but yes they've moved away from the books. The problem with this season is Jaime is Ser Arys Oakheart, Sansa Stark is Jeyne Pool, Ellaria and Trystane are aspects of Arianne (WHAT THE FUCK?!), and the golden company, the ironborn, darkstar, etc. just aren't around.
