I read one analysis a couple of nights ago that implied that the show runners no longer had the books as a guide, so they became clueless.
I have seen problems with a lot of popular movies of recent vintage. In classic movie writing the hero develops and you can see that person moving from a weaker person to a person strong enough to bring about good. Using an analogy as a man, modern show-runners leave me with the sense of kissing a beautiful woman through an inch of plexiglas, I see something happening but there is no meaning and no satisfaction.
As I took a little time each night this week to read GOT summaries and speculations on what happens next, I got the distinct feeling of wanting a good character to show up out of the blue to bring about a good ending. But I don't think there is the imagination in the show writing to develop that character over one episode to show that he or she was present all along, but not noticed.
When I read the summary on Cersei's end, I do think the show-runners got that decently right. One of the best ends to a vile character is to show that person as pathetic, afraid and remorseful at then end, silently wishing that he or she had made different more noble choices throughout life.
