You listed a lot of things that were foreshadowed largely in the books. I felt that the dialogue just about immediately fell off as soon as they ran out of book. Everyone felt very much on their own "tracks" and did not veer past that starting immediately with how they dealt with Jon just...coming back at the start of the season. Characters started teleporting wherever they needed to be, and episodes started feeling a lot more like a poor combination of big budget action scenes and desperate attempts to connect those by having two characters talk at each other alone in a room.

I feel like Jaime's failed redemption arc was missing something (maybe a couple books worth of further development and foreshadowing?) and the whole Bran debacle felt like it was really supposed to be something and they just "kind of forgot" to ever actually set it up.

I think there are some good reasons GRRM has had such trouble finishing the series and the show runners just never even noticed and steamrolled straight to the end.
