Last 2 seasons of GoT still hurt to think about.
It's not the ending that hurts it's how it got there. The last 2 seasons probably should have been 3 full seasons instead of the barely 1.5 we got and had a lot more build up/Dany descent into madness/Bran having some relevance that would justify his elevation to ruler, etc.
The suddenness of everything, the exposition, everything was just poorly executed. Too much money spent on CG dragons, not enough money spent on episodes telling the story.
The books can remedy my pain but have already waited so long. :(
