One day and five hours to go for season 2!
I think I'm going to marathon the season 1 Blu Ray. I haven't gone through all the featurettes yet and today seems like as good a day as any. I'm really glad I picked it up, the footage quality is gorgeous in HD and at any time you can hit a button and get the name and short background of whoever is in the scene, as well as where they're located on the world map.
There's also back story interludes that pop up at integral points in the plot you have the option of watching that tell of the history of the houses, religions, political standings, etc. It's really helpful when introducing new people to the story so you don't have to keep pausing every five minutes and explain everything to keep them caught up.
