God that was shit
It's amazing how much GoT changed, gone are the days when dialogue carried the show. Now it's just set pieces. As amazing as the production is, it's been incredibly shallow for a while now.
Once GoT made the switch from being about sharp dialogue and political backstabbing to "How much money can we spend on this amazing scene" it just never recaptured the magic of it's first few seasons.
If you removed the bullshit banter sessions from episodes 1 and 2 you could have delved into the NK more, maybe more backstory/insight in episode 1, the big battle in episode 2, then a retreat and kill him in episode 3. Maybe find a way to kill him that took more advantage of Aryas skills as opposed to her just running fast and jumping (I actually liked the idea of her wearing Brans face, assuming Bran doesn't need to die for that to happen).
As for the final 3 episodes... I'm past arguing that absolute tragedy of an arc, so whatever. But once again if GoT didn't feel like they had to put on such a huge spectacle they could have made Danys arc a bit more subtle. As others had said, have her assault the Red Keep and those civilians could have been the collateral damage that she sincerely regrets, that would have been more than enough for Jon/Tyrion to question Dany. Also Dany could justify herself without going against everything she's stood for. I actually think it would have made more sense at that point for Dany to cast Jon north because she feels she can't ever rule with him around. I would have been satisfied with an ending that had Jon in the north as he was, Dany on the throne, Sansa ruling the North for Dany but ultimately not trusting her and plotting her independence, and maybe float around the idea that one day Arya might take out Dany one day, and have Tyrion in doubt if he made the right choice. Maybe people would have hated that kind of ambiguity, but I think it would have found a nice balance between resolution but also y'know... not having to tie up everything so neatly.
The way they went with it, just ruined characters, created plot holes and ending up being ultimately very, very silly.
