I guess it's a little autistic but the tactics of the opening 15 minutes were "wait, what?".
Cavalry up front, then war engines... then, your infantry? Infantry up front, war engines behind them, cavalry on the flanks. You harry the rear or the flanks of the enemy with your cavalry. Their advantage is mobility. It doesn't make any sense to charge straight into a solid mass, you lose your advantage. You've got Jaime there who has been been shown commanding battles and you assume is versed in large formations of troops. You've got tyrion there. You've got Jorah there. Even Jon should have realized that was a silly initial formation. You've got a lot of people there that should have gone "wait a second, sure we're all going to die, but this is kind of a stupid way to do it".
And why are you shooting flaming catapult bombs AS your calvary is charging? If the enemy is just going to stand there... why not just lob bombs at them until they realize they need to move? Are you just HOPING to kill your own dudes?
That was the primary problem for me. Hardhome and the Castle Black versions of this actually had a sensible set of starting conditions.
The visual of the dothraki swords going out was neat enough, but it's not worth sabotaging the competence of your story just for that. They could have done a variant of that scene in the middle instead of in the beginning and it may have been even more impactful.
I know it's fantasy and all. But c'mon now. No one ever arrayed armies like that. Not even the british, who were famous for the simple solution of throwing more bodies at the problem.
