Everytime I started an Eddard or Tyrion chapter, I knew I was in for a ride. It was the exact opposite for Sansa, Dany and Catelyn POV's. Catelyn's chapters were boring because there were quite a few pages focused on her surroundings in a very detailed way. I was really struggling to follow on those pages. Dany was just plain boring for me and Sansa was mostly irritating, but she redeemed herself near the end.
