The disappointment I feel right now mixed with out right depression and anger over this final season is off the scale. I was so emotionally involved in every aspect of the show, the deep story lines, characters, back stories and the mythology of things like the lord of light, the prince who was promised etc...
Obviously when the source material dried up (GRRM's books at the end of season 5) and Dan & Dave (Dumb & Dumber) had to wing it things started going down hill, the character development and depth of story telling went to shit.
Even up to the finale I lived in hope that they would pull something out of the bag and was very much enjoying it up until after Dany's death which is when cast members started teleporting from all over the realm to King's Landing and there was a rush rush rush to get it over and done with so that Dumb & Dumber could further their own selfish career's and move on (b@stards).
Again I could have lived with it had they done things better after her death.... What I'd have done at this point was have Drogon to have torch Jon to death before torching the throne and then flying off to old Valeria with Dany's body, this would help clear up the next few scenes and give valuable extra air time so that the rest didn't feel as rushed.
I felt Jon was pointless after this point as was sending him to the wall. He was robbed of a) his fight scene with the night king (no problem with Arya's kill, but Jon should have got his fight first) and b) his rightful seat on the iron throne.
At this point to make the unsullied/dothraki somewhat happier it should have been Tyrion sent to the wall for his crimes to live out his days.
Bran should not have been King, for me the only viable candidate left with true honor was Brienne (with a twist to come) and Bran serving as hand. My twist would be Brienne on the throne but with a Lannister baby inside her womb to take the thrown eventually.
I was very happy with Sanza having the republic and being her own queen.
The final season has killed the re-watchability of the show going forward, for me anyway
