The intricacies of political maneuvering was never D&D's strong suit. They prioritize staging iconic YASSS QUEEN shots over the substantive storybuilding that should lead up to it.
Did you see how much fan service cinematography there was? Granted they were nicely shot, but they're hollow without meaning behind it.
It felt like they rushed through all the jibber jabber so they could finally make these shots and then pat themselves on the back for it.
Really makes me miss the days of the lower budget seasons when our chief complaint was the lack of battle scenes.
