I must admit that whilst overall the episode was fun to watch and the end deeply satisfying various the following aspect annoyed the hell out of me and somewhat broke my immersion.
- Who the hell commits 100% of their cavalry to the vanguard?
- Who the hell deploys the van without ANY support at all.
- Who the hell would charge at an enemy whose position they can't even see?
- Who the hell deploys artillery IN FRONT of the infantry?
- Who the hell deploys pikeman like that?
- Who the hell keeps NO RESERVE AT ALL.
- Who the hell, when defending a fortified position, deploys the majority of their force OUTSIDE the fortifications.
- Did they even have any archers? The time for those is NOT when the enemy is at the walls.
- They had a good few minutes of the enemy advance being completely halted by the ditches . . . . how was this capitalised upon? Staring contest. This is when that cavalry you held in reserve on the flanks would have been useful, huh?
- And let no even get in to how the WMDs (the dragons) were utilised.
UGGGGGGGGG
I have run through a few justifications for all this.
1) The night before the battle all the commanders appeared to spend the evening getting drunk and singing songs.
2) They didn't actually have any seasoned battle commanders, except:
- Jamie Lannister, not considered trustworthy enough, wasted in the infantry.
- Grey Worm, a former slave likely lacking the confidence to assert to his queen that he should probably be taking command of strategy.
- Tyrion. . . not a battle commander as such but good at planning and pulling off clever surprises at key moments. . . . I assume he ran out of ideas.
The real reason of course is that the show was more concerned with spectacle than making sense, to which I'd propose that it is possible to do both.
