Cities may not simply surrender. But this one have after the destruction of only some strategic portions. And the army just dropped sword. After that Dany goes berserk (I don't mind as I was expecting it, but as said the trigger was a little odd) and her soldiers start killing unarmed surrendered guys.

Yes Dany is less savage than those rulers, killing the slave owners and opposing families aren't that problematic, but it were cracks in the armor that she wasn't perfect and lovely ruler.

This season is sadly the worse of the entire series, and feels completely off in terms of pacing, writing, dialogue, plot, character development, and editing. The spectacle is at its best, but I never expected such a downward spiral for the series.

I'm not even interested in the final episode. This really does feel like comparing SW Episode 1 to Episode 4. It feels similar, but it is way way off.

It is sad the series was ruined so badly.

yeap, agree with your main points, it's kinda disappointing the final season is out of touch

I believe most of it was to shock viewers as usual, but this time it really didn't make any logic and was unnecessary if you think it is the end of the show

But she might have to strike "Protector of the Seven Kingdoms" from her name.

It makes sense in the context of everything that has lead up to this battle. Even early on Dany has a rather vengeful attitude and narcissistic personality but her most horrifying desires are kept in check by her closest and most trusted advisors. Jorah, Ser Barriston Selmy, and Tyrion all gave her council to show leniency, mercy or generally good advice (e.g Jorah's "There are good and evil people on every side of a war", something she doesn't seem particularly convinced by). The first two are gone and the third she no longer trusts. 

When she conquered cities in Essos, she was also welcomed, then loved by the former slaves which plays to her narcissistic personality. At the same time, she was indiscriminately brutal on the slave masters, regardless of their previous actions. A fact Ser Barristan pointedly makes and pulls her back from further brutality until his death. With the Dothraki she's worshipped as some sort of warrior goddess after she burns the Khals.

Now look at what's happened since she's come to Westeros. Instead of worshipping her as their rightful leader Cersei wages a propaganda campaign against her so she's feared. Tyrion's advice becomes less reliable resulting in significant losses to her allies to the point she no longer trusts him. She burns both Tarly's for not bending the knee. She then falls for Jon which ultimately results in her losing one of her dragons (one of the biggest symbols of her power). Then this season she finds out that she's no longer the strongest claim for the throne (and the person who is the right heir is well loved in Westeros). She loses another dragon, she loses the last of her most trusted advisors with the final one essentially telling her to burn the city down before her death (and coming from someone who was effectively a pacifist). She comes to accept the fact that she'll never be loved in Westeros in the same way as Jon. There is no one left that she would trust enough to keep her most brutal desires in check. 

In the final battle before she loses it, I saw all of the above coming to a head. This then combined with the fact that she realizes she could have done this from the start and the extra symbolism of the Red Keep as the catalyst/place where her family was killed starting everything bad that has ever happened in her life and I don't think it's any surprise that she completely lost it. 

Well, apparently Jon and Tyrion are there to represent the 50% of the audience that didn't see it coming! 

I actually find Tyrion's arc to be quite interesting. He's gone from one of the most devious and clever characters to one of the most naive and foolish in direct relation to him becoming more loyal and humane (which I guess most would see as positive character traits). Then again, it could just the volume of wine he's drinking. 

T'was but a single city of a mere 1 million peasants. What is one City in comparison to protecting the rest of the Seven Kingdoms from the White Walkers?

Well, historically the city guard would likely still be executed after the surrender.

But I see what you mean and... indeed. Which makes the screenwriters choice for the precise timing of even more baffling and clearly for shock purposes. It's deliberately forced so no one in the audience is supposed to sympathize with her after that. There's no moral shade of grey. At no moment your convictions are challenged. To people who claimed the White Wakers and the NK weren't interesting because it was manichaeistic... well, there we have it.

Honestly, Attack of the Clones, the second Star Wars prequel, with all of its flaws, actually manages to first showcase Anakin's issues, motivations and inner conflicts better than anything done with Daenerys in the last two or three seasons (which was basically looking depressed and snapping at Tyrion everytime he comes up with his idiotic ideas). Revenge of the Sith, then, it's Shakespeare next to this.

And saying the season having only 6 episodes isn't enough to develop the madness of her is also bad point, this gives over 7h of show. A movie have to do all that in under 1h30 and several do it greatly.

And Dany probably doesn't even remember his name and face.

Star Wars is dead. Rian Johnson put the thing to sleep.
