I for one saw it coming when Missandei's head got cut off right after she shouted drakaris. I said oh good she's gonna go psycho. Other build up is suggested when her second dragon is killed. I don't think it came from nowhere. I think her time after crossing the sea corrupted her like all the others except for Snow. But she kinda corrupted him too.
Oh and I saw a turning point in him too. I wonder if he whacks her.
yeah, i think that was the final straw for dany.
i don't know, you're right, it's not like it didn't come out of nowhere. it didn't. it was just executed so poorly that it doesn't feel genuine, which is i think where people are actually getting upset.
let's just decompress the miss sunday thing... the writers needed her to die to push dany over the edge. but she can't just die, it has to be in an unwarranted act of aggression. so we'll have miss sunday and grey worm take the unsullied to south and get ambushed. but, no army in the world is going to ambush the unsullied, so we need to have them go by sea, because the unsullied aren't a naval force. so we'll have dany push her forces beyond reason in order to separate the unsullied from the rest of the northern forces. then we'll have euron take out a dragon in the ambush just to solidify dany's loses. so we'll have miss sunday get captured, and then we'll have cersei execute her in front of dany. there's no REASON for cersei to execute her, we just want dany to be so pissed off that she burns king's landing indiscriminately.
it's become EXTREMELY obvious that the writers are working backwards to get things where they need them, instead of the characters driving the story. the books were ALWAYS character driven, and the show started out being character driven. it's what people have really latched onto for so long, and now that's shifted and none of the audience is on board.
nikolaj coster-waldau did one of those silly auto-complete interviews a few months back... someone asked "does jaime get redeemed" and nikolaj gave THE BEST answer for jaime. "Does someone who stopped a million people from burning NEED to be redeemed?"
i WISH the writers understood that depth when they wrote this season.
