It’s easy to lose perspective when hopes and expectations are smashed against a rock. Early GoT is still amongst the best all time TV IMO. The original Star Wars films didn’t lose their quality because of the prequels. The underlying love of what was originally created is still there even though the most recent huge disappointment can cloud that.
I’d actually argue there’s some flattering parallels between the Star Wars prequels and HotD, actually; a shared strength that people sometimes overlook for the Star Wars prequels, while the better comparison for Season 7-8 of GoT is as a less contemptuous and ruinous TLJ and TROS.
Not only are both HotD and the prequels, well,
prequels, but the both enjoy massive and creative increases in lore and a totally different status quo to their “older sequels”: for all that, say, Attack of the Clones was seen as the worst of Lucas’s films in quality and on a technical level, on a merchandise and franchise level is was still a rousing success because of the sheer
awesomeness of the Clone Wars concept as a larger scale war across hundred more planets and featuring massive armies compared to the OT, and all at the Golden Age of the Republic…
…much like how HotD gets to enjoy the premise of “Dragons vs Dragons” in the golden age of the Targaryens.
Lucas, while blamed for the quality of the PT, arguably elevated Star Wars’s place in pop culture because his “game” outside the films was so monumentally successful - his PT characters and stories were still making money and winning awards
decades later. Martin’s “histories” in Fire and Blood are very comparable in that as actual stories they’re kind of crap (since he’s just copying the dry nature of historical chronicles) but brimming with characters, conflicts, and ideas others can mine for massive output.
…Aaaaand I also think it’s time we acknowledge that the “the Star Wars prequels were disappointing!” meme should be supplanted by the “the Star Wars sequels were an embarrassing failure as an ending!” memes.
The “fall” between TFA and TROS was worse, and there’s no comparison too the Clone Wars as a franchise-elevating concept in the ST. The prequels were emphatically a greater success in the long run, while the ST started stronger and ended worse - with the debate being
where exactly that fall from Grace began…
