Well those people are fucking re.tards who will eat whatever shit is in front of them. So yes. The thing I've noticed about 'shocking' authors and killing off good characters is...well, they leave you without good characters. This problem is exacerbated in TV shows because you usually have limited characters to work with.
I've also read hypothesis that Martin 'sabotaged' the show, because he didn't want D&D to be more known for GoT than him. So he delayed publishing any material for them to work with once he saw how successful they were, while he did publish several novels and edited stuff until now. Martin also doesn't do outlines, so the outlines he gave them might have just been hypothesis. He writes in an organic way, seeing where the story drives him. So those outlines were probably next to useless. He also prided himself on GoT being 'unadaptable'. When that wasn't true, it might have been he took his ball and went home.
If GoT is known for a terrible finale, you only have Martin to turn to for a good one. Its kind of diabolical if you think about it.
