Outside of never being finished, I found ASOIAF to be kinda pointless, on the whole. I read the first 4 books and enjoyed the TV series much more - it felt like the editor GRRM sorely needed.
What else to read? Maybe Way of Kings by Sanderson, but it also struggles with pacing IMO. NK Jemisin’s Broken Earth trilogy are fantastic, but not medieval fantasy. Wheel of Time?
Dune or Lord of the Rings.
