I can’t think of them off the top of my head and generally it’s more a writing problem than the actual character. It’s pretty easy to spot when a guy is writing women badly as opposed to the actual character being bad.
And yeah, a lot of Cersei’s choices are awful but I can sympathize with them and I can’t say I’d make different ones if I was finally out of a relationship where I was raped for 13+ years. I swear when her father talks about marrying her off again I actually saw red I was so pissed. I had to put the book down for a bit.
