Sorry but there is nothing banal about George’s work. When he wrote the initial three books in the 90's, he completely redefined a fantasy genre mired in tired troupes. He brought consequences to the narrative, and in doing, breathed life into a tired genre.
Bash the showrunners all you want (I will clap that all day), but to lump George in is ignorantly disingenuous. The books are lyrical and weighted, and the exact opposite of the most of the show in almost every way (especially these latter seasons).
Have you actually read the books, or is this a gross assumption?
