Good Q. Those seasons were so bad it killed — or at least severely diminished — the casts’ star power. Who’s still hot from GoT?
It’s not like JRRM doesn’t have the issue of putting in too many strings that don’t pan out, at this point the books are almost too complex to actually finish.
PS I think the “stars” were more responsible for killing their own careers than the show..:
Kit Harrington, Emilia Clarke, Peter Dinklage, Lena Headey, Sophie Turner, Maisie Williams, Nikolaj Coster-Waldau, Iain Glen, ... whose not?
