It would be ridiculous to think that HBO would be eager to scrap it's most watched show of all time.
Rewatching the show, the only thing truly off is the speed in which we got there. The book prophesies are great, but some were never shown on the actual show. Dany supposedly loved her brother but she didn't feel much when he was killed in such a horrific way. One guy called her a bitch, she burns him alive.. she locked her handmaid in a vault to die. Hung the masters up at slavers bay. We overlooked it, because they were seen as bad or we didn't care about those people like for example, Margery. Cercei- Dany not that much different, just got the Dany sympathetic POV. Maybe George RR Martin lesson is in war (and politics) people often only see one side.
