Even Game of Thrones only got so far - it spent MUCH more effort (and money) on trying to convey the Stark Lannister civil war, and STILL ended up awfully vague and unexplained over and over again.
I thought early-season (roughly 1-4) GoT political intrigue was almost always really well done, mostly because the author Martin was taking so much from British history. The intrigue had a feel of versimilitude that the Witcher this season entirely lacked. Maybe it's not fair to compare them, but the Witcher did choose to play in a pool where it's clearly completely out of its depth. I agree they should have stuck to intimate monster-and-village storytelling, very much its strength.
