Bump...Just watched the first 3 episodes of Season 4. Adrien Brody and Littlefinger have made appearances. While not yet available on Netflix, it's on BBC2 and other places on the web if you are resourceful.
Once you get through the first 10 minutes of ep 1, shit picks up steam from there.
Yeah ok im ashamed it took me this long, but I finally blasted thru season 4. God damn. They did not fuck around this season. Best one yet. It did get a bit weird at the very end of the last episode when they were trying to use the remaining time to set up season 5, but I can forgive that. I was kind of skeptical about Adrien Brody at first, but he did alright.
