10% of the series devoted to "previously on GoT". Nothing much happens aside from a swift metaphorical kick in the nuts to some peripheral characters and the writers chanting "we ain't in Kansas no more, you haven't got GRRM looking out for you now".
This is the trouble of effectively trying to tell the story of WW2 from the point of view of everyone involved. When Winston Churchill tried it he ditched the idea of describing what people had for breakfast every day instead opting for the grand strategic view. This is GRRM and the tv writers' downfall. You can do one or the other, and if you elect to do the former you have to restrict your vista.
Keeping with the WW2 metaphor I'm pretty sure if you did examine the deeds and intentions of all the major players they wouldn't coalesce into a coherent single thread. There would be radical departures from the overall story all over the place. Accordingly it's a waste of time people criticising the writers for "out of character aberations", that is the lot of human beings. We don't all conform to some perceived norm.
Accept the series for what it is. Glamourised medieval pap with boobs.
