I respect your take but disagree. First there is complaints about how rushed the season is but then we want the setup which occurred in the previous episode to all happen in one episode. Grey Worm was still looking for justice even after the torching of the City. The death of Missandei wasn't something that could be forgotten so quickly. Same with the dragon. The betrayals of her inside circle was also part of the setup. The face she made as she began torching the City was the exact same face she made after Missandei was beheaded. Finally, we now found out that she knew Tyrion had also betrayed her.1. Rheagal is killed during the battle of KL. Anyone could buy that watching her dragon/child die could have triggered a f*ck this reaction causing her to burn the city (much like Cersei’s trauma from losing her children). Killing Rhaegal the way they did was asanine for so many reasons. She could have torched the remaining living sht out of the fleet with Drogon (like she did a few days later, along with an entire city and army.). But worst of all they threw away the perfect setup for why she would lose her sht in the moment of battle.
The zig zag pattern was awesome effects. Again why rush it? Also, Cersei was witnessing the destruction of her City realizing the mistake she made. The tears flowing down her face as she watched the zig zagging were precious.2. Her lust for the throne, essentially madness, leads her to torch the city for reasons that make sense. Cersei refuses to surrender and, rather than hide in the Red Keep, escapes to the city amongst the people to avoid Drogon. Despite the insane civilian cost, Dany justifies frying everyone in her quest. Believable and within her character’s nature...would still cause the same feelings from Jon, Tyrion, etc. Instead she actually risks letting Cersei escape so she can zig zag pattern KL for absolutely no reason.
With all due respect, you don't know much about mental health if you think insane people look and act insane all the time.Bonus: the other reason the “insanity” angle is so dumb is because it’s sandwiched in between scenes where she appears sane. She is sane when getting turned down by Jon the night before and discussing her strategy. She is sane immediately after the city torching (even her face has returned to healthy looking and her hair normal again.)
I didn't particularly like the last episode but I'm ok with the way the season evolved given it was only 6 episodes.
