So with some quick episode scanning I figured out you could split the last 4 episodes of thrones into two roughly 40 minute episodes (there's actually very natural breakpoints in each), making 10 less stuffed ones and adding time and pace between episodes for travel, breathing space, or for feelings to settle and/or cement, etc. Season 7 is actually harder because it and its episodes are more normal, but the last 2 can also be naturally split this way and then I think you turn the first 3 episodes into 4 because they just stuffed a shit-ton in them collectively. Actually, splitting the overstuffed though not overlong third episode is probably best despite the short 30+ minute runtimes.
Anyway, without further ado, my super nerdy proposal for restructured 10 episode GoT final seasons, with episode titles and estimated minutes included ("please forgive the crudity of this model"). New episode titles are in quotes. All writers, directors, etc remain the same since episodes are only split.
Season 7:
Dragonstone 59min
Stormborn 59
The Queen's Justice 33
"Queen of Thorns" 34
The Spoils of War 50
Eastwatch 59
Beyond the Wall 39
"Ice & Fire" 34
"The Dragonpit" 46
The Dragon and the Wolf 37
Season 8:
Winterfell 54
A Knight of the Seven Kingdoms 58
The Long Night 43
"The God of Death" 42
The Last of the Starks 47
"Dracarys" 34
"King's Landing" 46
The Bells 37
The Iron Throne 46
"A Dream of Spring" 37
I don't know why the showrunners didn't just do this though, and/or beef up or add some scenes to fill them out, both from a storytelling and length standpoint. Replace the cut corners, so to speak. It's like they went with their first draft and were so into reducing and refining instead of expanding on anything, even needing stortelling in the previous episode and after-show segments.
I think part of it was wanting to make movies essentially, like they were, and thought everyone would be, into the feature length episodes, like, "we're going all out and expanding TV to a another level!" Which, while technically true, doesn't mean as much if you sacrifice the foundational storytelling basics of your own show in the process. Super cynical take everyone denies: they did EVERYTHING the way they did, big hurried cinematic action episodes, to basically audition for and facilitate their jump to Star Wars. I bet Bob Iger was getting early cuts of these extra cinematic episodes. =)
Rewatching some of it, I don't think the writing was really worse than the Dorne nonsense in season 5 or a lot of season 5/6 stuff in general, but it all benefitted from fitting into a greater, sounder narrative structure that would accommodate those points of weakness so you could tolerate it and come away thinking, "that part was bad" instead of, "geez, it's bad now" or "it's ending badly" because there's not going to be an opportunity to do better. The show basically always had some suspect writing, but like a volume shooter it's better to go 8 for 20 than 4 for 10. Quanity was their friend.
In this case, breaking the episodes up would have meant a lot more decent character driven or action episodes than overstuffed one's marred by fatally flawed or rushed moments. Even those moments would benefit from being more centrally focused; the death of Rhaegal for example, which dragged down a whole episode that was at least OK and largely about something else before that. Plus, if the whole episode was essentially about the dragon dying, it feels a lot less like another random moment among others, but is seemingly given the breadth and focus it deserves.
Food for thought before this thread sinks forever or gets revived for whatever bad spinoff(s) will come.
