We're going to have to agree to disagree about this. In the show, her pigheadedness is just an excuse to tell us how incredible she is because "she's not a normal girl". It got her into trouble with the Faceless Men but come on, is it really trouble? The only way I can be assuaged by this is if they actually work with Cersei to stop her.

She has the least impactful character flaws and suffers the least problems because of them.

Cersei has to walk naked in front of all of the people she lords over while being humiliated.

Jaime loses his fricking hand.

Hound can barely withstand fire and panics when he sees it/loses his control.

Jon is fricking killed for being an inept leader.

Dany is worthless in battle and only supported because she has dragons.

I could go on for days how fleshed out the other characters are. Arya "gets a little bloodthirsty and it gets her into 'trouble'". Sorry, not gonna fly. Nothing she has done has brought consequences upon her other than being blinded for not listening -- but as I said, when bad things do happen to her, it's only used as plot armor to further increase her glory.

Kidnapped? Save a legendary assassin and become his mentor.

Don't listen? Be blinded, but only so you can be an expert fighter in the dark against a trained assassin with more experience than you.

Get concussed? Run around like you're playing a third person video game because you're definitely not looking at where your enemies are.

Literally one of the worst main characters of the show where the only bad consequence that happened to her (with actual impact) was her family getting butchered (not being one of the victims of the butchery which is decidedly worse).
