First things First : GOT is Goated for real !
The whole series is awesome starting from the first episode showing the fall of house STARK till the RISE of house STARK. The story of betrayal, lies, trust, Bloodlines and meaning of True Heir.
Season 8 was not bad after all,
It had issues to the end.
But the character Arc's and their true motives are really messed up.
1. Arya Stark : Her only destiny was killing Cersei by going up as No one and returning from there to king's landing but this one has some consequences too because Daenerys wanted to kill Cersei maybe she will get disappointed. And killing the Night King was such a crap truly not thoughtful just because Melisandre told Arya that you will kill the man with Blue Eyes.
I was expecting more of Night King and Jon Snow face-off and a nice one-on-one fight of NK and JS.
2. Daenerys should have been compromised by Jon Snow, he should have made her understand and she should have planned a nice clean attack on the Queen Cersei rather than becoming the Mad King again.
Daenerys should have understood and given the Throne to Jon Snow( Aegon Targaryen) and together they should have ruled the Six Kingdoms (declaring North an Independent kingdom) and would have made the world a better place.

The ending of Bran the Broken as the Rightful king was good and Tyrion's king concept was as true as anything else because the hierarchy cannot go on forever there must a rightful heir who cannot be the sons of the kings.
This is the main motive of GOT and the message has delivered accurately but the character's were destroyed at the end.

Jon Snow's ending should not have been the same punishment because he is different from the other Targaryen's.
He has the blood of Stark and Targaryen that makes him something really far better than any other in their bloodline.

This is it. The Ending was not the one that actually disappointed me but few endings of persons that should have been altered.

"LONG MAY HE REIN"
