More Thrones. We need more.
On the plus side, 10 episodes (or soon to be seven) per season is the perfect amount to produce top quality content. On the down side, it means we only get 10 episodes every year. That's why every shred of Thrones is lapped up and savoured.
In such a huge world, there will always be storylines omitted and events overlooked. Despite David Benioff and D.B. Weiss having 60 hours to play with so far, they've still only scratched the surface of what could be shown from Westeros, making Peter Jackson's feat of condensing J.R.R. Tolkein's Middle Earth into a trilogy even more impressive.
Every second in Westeros matters, both for the characters in the world and the creators of the show. The story must be tight, sharp and tense, and that's why plenty of material was shot but failed to make the cut, including the original Pilot episode where the roles of Daenerys and Catelyn were yet to be given to Emilia Clarke and Michelle Fairley.
Once the final Pilot went to air, the show has leapt from daring height to daring height, and the high standard has meant plenty of good material has been unfortunately consigned to DVD bonus discs...
