Daenerys' rampage after King's Landing surrenders makes COMPLETE SENSE

Correct.

And up until she's been very aware of that, and terrorized people with the dragons selectively, leaving most alive to obey her from then on. Like when she burned one invading ship out of a hundred and accepted the surrender of the other 99. Or when she fried the Tarlys, and let the Lannister soldiers who saw it go free if they promised not to fight her again, she knew they wouldn't.

They really have made a mess of the Mad Queen thing, and it could have been so great!

She didn’t go there to rule Kings Landing only, that’s just the capital city - but to rule all of Westeros. The other cities have plenty of living people left who will hear of it.

As much as all that made sense, she's his aunt. As Varys said. The marriage might have still been an option if they managed to reignite their passion in that scene in episode 5 - but they just couldn't do it. After that failed kiss, any politically sensible options you described were thrown out of the window.

Makes perfect sense to me.

that's what hillary did

"And his claim to the throne is still stronger than hers."

Only in the most technical dynastic terms. In realpolitik terms, she's the one with the dragons and the armies, and the well-known Targaryan parentage, but it's the dragon and the armies are the reason her claim is being taken seriously. Without them, she's just Viserys's sister the Beggar Queen. To the rest of Westeros, Jon is nothing but Ned Stark's bastard and a deserter from the Night's Watch, even if he's been calling himself Kinginthenorth.

Honestly, she and Varys are the only people who ever really cared about Jon's parentage, and now she's the only one. And if she were in her right mind, she'd see what a minimal threat to her ambitions he really was, but going nuts in the course of a week does cloud the judgement.

They made a point of showing there was wildfire stashed in some areas. One reason could be to reference the end of season 6 when she blew up the sept, and it shows the scale of her damage compared to what Dany just did.

In the scene where she tells Tyrion she caught Jaime, she also said Cersei is good at using her enemies' weakness against them. She sees Tyrion's plan with the bells as the kind of mercy that could fit that weakness. Dany views mercy a bit differently in this moment- basically arguing that the ends justify the means, which turns it into a strength in her mind. However, she is not completely sold on this position. She knows Tyrion's plan is well-intentioned and probably the right thing to do.

Whether or not there was really a plan in place (probably not), Dany knows that Cersei could very well be using Tyrion to lay a trap. They get near the Red Keep and she blows the wildfire. Dany hasn't decided what she is going to do until the bells start to ring. Then she saw Cersei in the balcony while grieving her losses, also remembering how badly Tyrion's advice had recently turned out. She ultimately chose to go with her instinct, which has always since day 1 been fire and blood.

She was loved in exile, to some degree. The Blood Riders and freed slaves who saw her in the ashes of her husband's pyre with baby dragons loved her as long as they lived, the freed slaves of Mereen, Astapor, and Yunkai loved her, even after they realized that freedom meant homelessness and poverty for most. Of course the Masters and their allies hated her, as did the Baratheons, so she actually was being used to being loved by some of her subjects.


However, for her to go into a homicidal fury because the Lords of the North didn't fall worshipping at her feet is just silly! What they should have done is establish that nobody in the rest of Westeros believed that there had been another Long Night and that she'd saved them all, at the cost of her beloved dragon. Because even in Westeros, nobody believes in Zombies until they've seen one. That'd make sense and provide a valid reason for her to be pissed at all the people of Westeros, right?

"However, I do see other people's point that the build up to the insanity wasn't handled well, and I can't see how anyone would see what Danny did as a good strategic move."
I don't think what Dany did was a good strategic move, but I think part of the point here is that she is no longer making the correct decisions. In terms of the love-fear arc, I thought it explained her (clouded) judgement perfectly. I agree they needed more time to build it up, but unlike many others, it didn't ruin anything for me - I absolutely loved the last episode!
