She didn't exactly give all those serfs an opportunity to live in "my new world" under a dubious distinction between slaves and serfs. As the "breaker of chains", the Kings Landing serfs didn't quite qualify as slaves. That's not exactly madness. Did anybody expect her to draft a Magna Carta, abolish the landed gentry, and give the serfs of Kings Landing 40 acres and mule? Of course not. From the serf's perspective, it would be "meet the new boss, same as the old boss" which from her perspective would present a threat.
I'm sure the conclusion was disappointing to many, particularly the fan girls, who expected the heroine to bring freedom and justice to the world even though there was little evidence of such inclination. Inside this fantasy wrapper is an allegorical setting in the Medieval dark ages. Nobody in power is interested in upsetting the feudal system, with the writers beating you over the head with it when the idea of a popular vote for king was laughed off.
The choice of Bran is a reasonable one, a first turning of the page toward Enlightenment, from a warrior queen or king to the "visionary", even if the fact that he literally has visions is bit trite. There's value, one supposes, in having somebody lead who can plumb the past for the "historical facts", the embodiment of institutional memory, while being able to fly off as a raven to see what's happening first hand around his kingdom. The fact that the Night King had Bran as his primary target, for reasons not explained, should have given viewers an inclination that he has some special power over evil.
Jon Snow? There's a price to paid for choosing ****** over duty until it is too late. It left him vulnerable to being a pawn in political compromise.
My complaints relate to artistic execution. Here are just a few examples out of several:
- Some found a contradiction in Bran's "this is what I'm here for" and "I don't want to be king". Call it a preception of duty or fate over personal inclination. What was wrong is the way the latter line was delivered. Bad acting or writing or directing or all of the above, but that idea of duty or fate was not effectively delivered.
- The dark filming in the White Walker battle may have been an artisitic choice. Or they may have gotten to editing and found the CGI was coming off fake. Either way, it didn't work. The one-on-one fights in the bowls of the castle amount to filler.
- In the White Walker battle, the dragons make a couple of strafing passes then get lost in the clouds. I was saying then, I think out loud, "why don't you fly up?" We cut away from them and don't come back to them for what, 10, 15 minutes? What have they been doing? And then there they're wandering around above the clouds. Why not come in low for more strafing passes? I was thinking 1) the dragons don't have that much fuel and 2) fear of the Night King's spear. Which takes me to the next two points.
- Prior to the final battle, Tyrion was certain the Iron Fleet would be taken out. I expected some twist in the battle plan. If stupidity (or madness?) is doing the same thing expecting a different result, then this qualifies. She comes flying in just like the last time, with dozens of those giant crossbows waiting for her. How come they're not all firing? Lucky for her. And by the time she strafes the crossbows on the city wall, they're not even pointing in her direction. Lucky again, and entirely inexplicable.
- So, what we eventually find out is (1) these dragons have a bottomless amount of fuel and (2) any fear of a single Night King spear was supposed to be more of a deterrent than dozens of crossbows previously proven to be quite affective? Heck, the fate of the human race hung in the balance in the White Walker battle, where the stakes were much higher. Some dragon risk was called for in the White Walker battle whereas what we got was avoidance and, in retrospect, the wherewithal to lay waste to the White Walker army long before they reached the castle walls as was evidenced in their ability to lay waste to an entire city. That doesn't get you to an hour and 20 minutes, however.
- I was waiting for Arya Stark to apply her shape shifting abilities to the proceedings somewhere in this final season. Shift to a White Walker in taking out the Night King, perhaps? Instead, she flys out of the sky, a skill we didn't know she had? Or once inside Kings Landing, on the hunt for Cersei? I guess she forgot how.
In the final analysis, this was an entertaining TV series. The problem for me was not who won and lost, who was mad and who wasn't. The problem was starting with the premise of 8 hours and then creating a story arc that fit, with a bunch of logical inconsistencies and a lot repetitive wooden dialogue along the way. They could have gotten to the end point a lot faster in a more coherent manner. That doesn't make as much money.
In the final analysis this sh*t ain't Aeschylus or Shakespeare. It's not even "The Sopranos" or "Deadwood" once you strip away the expensive special affects. It's fun to analyze but not something in which to have gotten emotionally immersed even before this defective final season.
Let's just say there is history still to be written.
