Bran and Sam should have written A Song of Ice and Fire. Sam wrote the prose and Bran did all the research.
Bran should have been either King of the North, Master of Whispers (with his own army of literal little birds to replace Varys), or an advisor to the new king or queen of Westeros, not king himself.
‘Who has a better story than bran the broken?’ is blatant meera and jojen reed erasure (osha and hodor as well). Osha busted them out of winterfell, jojen showed up with his green dreams to guide them to the three eyed raven, and meera dragged his ass home after. The only thing bran managed to do is touch the night king and get a bunch of people killed (including the last living members of an entire species). Bran in general has very little agency in his own story. Jaime throws him out the window, robb leaves him in charge, theon takes the castle, the three eyed raven decides to train him. Even when he finally seems like he might actually do something in the battle with the dead, he just doesn’t.
I saw the point made that if the idea had been that the person with the most stories, that knows the most history, should be king, then this might work a little better. A 'those who don’t know history are doomed to repeat it’ type thing. But as it stands, it’s such a ridiculously unsupported choice.
