The Sansa/Arya reunion was flat...poor writing. I can't think GRRM signed off on that scene.
Even thought the battle had its moment, there was implausibility that made for some cheesy moments, such as Bronn handling the crossbow so effortlessly, and getting off, like, 5 shots. And cinematographically speaking, I would have like lento have seen a better wide angle shot of the battle.
And for Christ sakes, you have an effing dragon....come in from the flank and cook the whole line in one pass...minimize your exposure. The enemy line will break and let your cavalry do the rest. I was thinking if Jaime possibly survives this, I'm going to start writing screenplays.
Other than that it was pretty good
