I just hope we see some epic battles this time. The first season was great, but I thought it was a bit of a cop out how they cut the big battle at the end out by knocking out Tyrion then having him wake up after it was over. The book was different in that instance and better for it. Though it was quite a clever way to cut production costs lol
Not to mention time constrants too... Sure the Whispering Wood & Tyrion fighting in the vanguard were big battles for the first book, but really they're just the opening skirmishes.
I think it was more important to the story to focus on the political intrigue & backstabbing going on in King's Landing, as that's what really drives the main story and thus gets the ball rolling for almost all the other main events to come.
(poor, poor Eddard, he never stood a chance even though Varis tries his damndest to save him!)
Most of the trailers for season 2 do show some quick snipits of Blackwater Bay, so we will get to see at least 1 epic battle this season!
I'm really hoping they keep the initial meeting between Tyrion & Cersi exactly as it is in the book though! Classic Tyrion moment for sure!
Also I like how Dany is going to be a bit more kickass this season! And Drogon going apeshit nuts as well!
My only real worry is what are they going to do come season 4 in order to stop it from being too damn boring?
