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. 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. With all due respect, you don't know much about mental health if you think insane people look and act insane all the time. I didn't particularly like the last episode but I'm ok with the way the season evolved given it was only 6 episodes.
