Have you read the books? If you haven't you must, fuck what your friend said.
Every chapter is reading from a different characters POV so people that you despise in the beginning you start to understand why they did what they did. And vise verse, sometimes you kind a character or cause awful from reading from other POVs. Cersei's POV chapters don't start until the fourth book, and I'm almost finished but I have started to hate her even more because of her POV. She's and entitled little cunt from start to finished. I don't know what the next few books will bring, but unless she goes through a huge transformation she will always be a stuck up cunt.
