Dany doing what she did makes perfect sense tho. Think of everything she’s been thru:
-Agrees to help Jon when she didn’t have to, only to have one of her dragons die
-The Guy she fell in love with actually turns out to be her nephew AND the true heir to the Iron throne (something she’s spent her whole life trying to achieve).
-she loses half her army and Jorah in the battle of winterfell.
-She STILL loves Jon and wants to be with him, but he’s very hesitant now. She’s most likely heartbroken.
-She’s noticing how everyone is more drawn to Jon than her
-loses another one of her dragons
-watches Missandei(her best friend) get beheaded by someone sitting on her throne
-trusts Jon to not tell the secret only for Jon to tell it anyway. People are going to find out the truth.
-Varys “betrayed” her.
I’m not saying I agree with what she did. She spent all this time trying to be different from the other tyrants only for her to become one of them at the end. Sad but it’s very understandable after everything she’s been thru. Plus the last thing Missandei said was “Dracarys”. She most likely just carried out her last wish
That doesn't fit Missandei's character at all though. Her whole thing is that she's been a slave all of her life and she convinces Dany to take more peaceful approaches in order to avoid bloodshed and save as many innocent civilians as possible. Sure, she was about to die, but it is still kind of lame of them to throw out her entire character development and arc for her to essentially tell Dany to burn them all (including a bunch of civilians she normally would convince Dany to save).
Like Juggs I don't have much of a problem with Dany burning KL, but the way they did it made no sense and was purely for shock factor and to make the viewer hate her more. If she was really this hellbent on blood, she would've burned the city from the start. I don't buy the fact that the sound of the bells causes her to snap. She had already been betrayed by Jon, Varys (another character whose entire story arc was thrown out the window in like 2 episodes), Tyrion, and watched Missandei die. She was already out for blood, so why didn't she just burn it all to start with?
It is pretty obvious that D&D aren't good enough story writers and can't match the nuance and interesting character development that George R.R. Martin does. The whole point of characters like Tyrion and Varys is that they can always think ten steps ahead, but that involves the writer thinking ten steps ahead and making sure that everything makes sense within all of these characters and their relationships. The reason their characters were dumbed down imo is that D&D can't write in the same way GRM does while keeping everything consistent.
I don't even blame D&D really, i'm sure when they started the show they expected to have another book to work off of. Now they don't and they have to end the most popular show on television based on a book series filled with nuance that they can't possibly match. My guess is they only wanted 6 episodes because they knew they couldn't possibly end it in a satisfactory way and wanted to get it over with. So they came up with an idea of how it ends in their head and threw away all the other character development so that their ending made sense (which is bad writing, imo).
