Great finale, this has been a strong comeback season imo. However, two things...
1. I'm mad that Cersei always wins, she's had hero plot armor from season 1.
2. Speaking of plot armor, now Daenerys has an army 1,000,000x more powerful than anybody else, so... who is she planning to steamroll with it? Since steamrolling seems to be her style, weak as she is at diplomacy and charisma and all that. Just seems like she's been the rich getting richer for as long as Cersei has had plot armor. Pretty boring, despite the cool visuals. Though if I'm answering my own question, it looks like the showdown next season will be Cersei vs Daenerys. I would expect it to be interesting, except mutant mountain and wildfire isn't going to do a solitary thing against dragons.
Sucks Margery had to go, she was smart and would've made a good ruler.
Edit: bold prediction!Jaimie kills Cersei and becomes the first ever double kingslayer. Now that she's got what she always wanted, she's going to be even crazier and probably do exactly what the mad king did.
Cersei is queen to a terribly weakened kingdom. She got what she wanted, at a grave cost. Her position is tenuous.
Dany has a huge army, that would steamroll through the Seven Kingdoms at full strength. Guess what else in this story has a huge army that would steamroll through the Seven Kingdoms at full strength?
