I believe that her arc is a conqueror's journey disguised as a hero's journey, and it was done so well that everyone felt betrayed. This thread is for hot takes, so there's mine. 😄
See here's the controversial take. I don't agree with you at all. It was literally built up for the entire series and was the only natural conclusion. She was literally saying "I plan to break the wheel" from the start. That is not language a peaceful person uses. Her goals to begin with were those of a conqueror, and what we got was the natural end of that ambition when it crashes into reality.
I think it was done beautifully, and the fact so many people bought into her side of things and felt betrayed is evidence of how well done it was.
While there were some truly awful moments in the last season of game of thrones, danaerys' arc was not one of them. Her going nuts was hinted at from the beginning and I wouldn't have had it any other way.
It doesn't hurt to ask, though I think generally phrasing it as "I would appreciate any feedback on my application" is going to get more real responses than asking for a reason you weren't hired.
I'm from the area and this is a really big win. We've had a string of terrible mayors beating promising progressives, so this is a long time coming!
