The main problem I have with the last episode is the result of the main problem I have with episode 5 (though there are other practical issues I have with 5), which is that I don’t think they really did a convincing job of developing and portraying Daenerys’ character transformation, or her or Jon’s / Varys’ / Tyrion’s actions.
I don’t believe Varys would have been so convinced that he would have taken the action he did that soon.
I don’t believe Daenerys would have chosen to burn 99% of King’s Landing after the bells rang. They showed it happen in a very wrong way, just to justify to the audience the others turning on her. Lazy ass weak writing strikes again, as it did to the tactical details in episodes 3, and 4 (and some aspects of 5).
I don’t believe how Tyrion or Jon turned on Daenerys in those ways, even given her actions.
And that’s about all there is to talk about of much interest.
I’m glad those writers are done half-assing the show, because clearly they ran out of interest or ability to develop it a few years ago, and were running on empty in Season 8, as far as being able to do more than make it pretty and provide an ending.
The world was a detailed, complex, interesting place worth exploring when GRRM wrote about it, and the TV authors left it mostly empty.
