Unless by “general plotpoints” you mean like an elevator pitch of what happens in the season, I guess from that very abstract view you are right ;)

I mean yes, you may not be aware of the development of the show but basically GRR Martin gave them basically a list of checkpoints that happened in the most general sense ie important character deaths, who stays alive at the end to control the kingdom, important character events and/or etc. D&D basically made their own path to these checkpoints and sort of improv’d the rest of it. Jon being revived, Dany going mad, Bran ending up on the throne. These are all likely meant to happen if the books ever come out. The problem is always the execution. I know book fans have some book exclusive characters (Lady Stoneheart, Patchface, etc) but realistically they probably aren’t that important in the grand scheme of the series.

Tyrion Lannister, dwarf and exile, stood resolute upon the prow of the majestic vessel, the Wind’s Grace, its timeworn planks creaking beneath his weight. His mismatched eyes, one green as the emerald depths of the Whispering Wood, the other a glimmering pale amethyst, stared out into the boundless expanse of the Narrow Sea. As the ship cut through the frothing waves, the wind, bearing the salty tang of the ocean, lashed at his face, sending raven-black locks of hair spiraling across his brow. It was a gusty tempest, much like the swirling turmoil that had beset his life ever since he had been forced to flee the shores of Westeros. The crimson light of the setting sun cast an ethereal glow upon Tyrion’s countenance, accentuating the shadows that danced upon his visage, mirroring the darkness that had shadowed his soul for far too long. His lips, full and pursed in contemplation, were tinged with a touch of melancholy, the weight of his troubled past etched upon his face like the lines of a map charting the arduous journey he had undertaken.

I would summarize it as wordy.
