Welp I think the this thing kind of jumped the shark.
I think there's a lot of weird and annoying things going on, but none worse than the fact that the way they've handled Sansa and Ramsay. That whole situation is just pure sacrilege. The idea that they should ever have those 2 characters collide is barf, and a product of the excess attention demonstrated them for fairly arbitrary reasons. I wish show creators would accept that a lot of the time a character's value stems from it's exact time and place, not everyone should be a focus just because someone "likes them," the question is, does the story require that the character be the focus?
Unless Aegon comes riding of the thunderclouds by the end of the season, I'm inclined to say this show has gone as far as it's gone. It'll still be popular and entertaining, I'll still watch it I suppose, but this whole continual uptick in viewers and excitement season to season and so on is basically at it's end I'd guess.
Also I'd be someone is going to remake this series again in like 10 years (with a more faithful adaptation) and everyone will be arguing about who was the best Ned Stark and all that.
