The GOT reason to Hit because of rising of Dany character,background score upto 6 seasons ending & curiosity to next (level)season. She's saved many people, their dragons burnt sins of enemy. D&D has given interview that After bell Dany seen lannister sigil on throne building,1) then she could have burn only that, why burn innocents 2) What was tree eyed raven doing while burning people, he could have stopped 3)valyrian steel has made from valyria place & dragon bone so why knight king wasn't burn by Drogon.
5) Dany would burn Iron Throne with Drogon beacuse the thrones main reasons for all clashes of families& people.
So many lacks in story D&D ruined the Story because they wanted to kill the Daenerys character......So Disappointed.
