Looking back...the entire season was a prelude to war...as was this episode. All sides are set, the armies are approaching, the dragons are live. In that context, it was a good season. They could've shuffled things around to make it a better buildup to this 'climax' to make it feel more like a cliffhanger...like have the scenes in Dorne like 2 episodes ago, and Rhaena running thru the world map on some Final Fantasy shyt...that could've been episode 5 or 6...etc...
Next season should be WAR, very action based.
