So, two comments from the premiere:
1 - It feels like episode 11, rather than season 2 episode 1. This is a good thing. Far too often, the production and writing crew come back from their break, their flow broken, and season 2 of the TV show feels like something different, a brand new 'episode one' rather than the continuation. This happened with Deadwood, Mad Men, Battlestar Galactica and countless others. Game Of Thrones has avoided this trap.
2 - Maybe it's because everyone is now much more comfortable in their various on-screen and off-screen roles, but the quality of the writing, direction and editing seems to have taken a noticeable leap up. Although the plot necessitates none of the singular moments can rival anything in season one, the overall feel of construction of the scenes seem far higher than the previous season's average.
Looking forward to more!
