I find it dumb as heck that they forced Jon to leave for a Wall after Unsullied and Dothraki left Westeros. Everybody have to stick by their word now?
The whole season 8 felt like a recap episode of like two seasons it was like watching The Last Airbender, even worse because we could watch the actual season of Last Airbender. Here we only have the recap. It seems Martin left the directors a quick pointers what have to happen and hoped they will fill out the blanks, but they just filmed the pointers and called it a day.
Some characters were just cut off like Asha Greyjoy. Her character was clearly going somewhere in earlier seasons and they just handwaived her and didn't even included her fleet in the final battle.
