Game of Thrones is now in the afterglow of its first season on HBO, and it's been a huge hit. It's the right kind of costume/period fantasy-action-thriller-drama trashiness to draw World of Warcraft addicts and intelligent popcorn-TV seekers alike into its special brand of indulgent fast moving mythic storytelling.
OK so I'm late to the party, but I have to point out that what I REALLY like about the show are its opening titles. Directed by Elastic (the CG company also behind Rome and Big Love's opening sequences). The GoT titles are not just super beautiful, they're packed with an insane amount of thought and detail - if you're interested in the intricacy involved, read about it here.
