It was idiotic. However, I did like the tension of watching the lighted swords slowly blinking out in the distance as it all got quiet. Also, the shot from the ridge where Dany/Jon were watching while they charged was a beaut. Didn't make any goddamn sense at all, but it was pretty.
I'm a software engineer. My wife is a nurse. We were study buddies through our educations. If we were particularly caring about how realistic TV shows were, we couldn't watch TV. I expect that show creators in general don't know shit about shit so I'm not often disappointed. I can only see so many "hacking" scenes or shitty needle use before I just give up.
Its not really about them not knowing shit though.
We accept that realistic sword techniques and battle formations dont translate as well to screen in the same way we accept that real life hacking isnt as exciting looking as fast typing and multiple flashing screens.
This is more about the context of what is happening and a laziness in applying the glue that connects the characters goals with the show runners vision. They have no shortage of people they could ask about how such a battle might be approached and why such a force might be required to venture out. This could be explained with a scene or two replacing the existing preparation scenes if they cared to.
When I watch MacGyver, I dont care that you cant pick locks with a SAK bottle opener because that show has built its brand on silly contrivances.
GoT has built its brand on being the show with dragons but where decisions and actions have realistic consequences. A boy is left paralysed with no magic cure, the noble hero gets outflanked and killed by bad guys, the seemingly invincible warrior gets an infected minor wound and dies.
The show has abandoned such concepts now and is basically just an american style soap opera with rich people giving evil speeches to each other and one upping the shocking betrayals they can pull off. Now that the night king is gone, most of my friends are telling me that this 'intrigue' is all they ever cared about. Which....fine. soap operas are popular for a reason and I still read comics and Jack Reacher.
But I just dont think its innocent lack of knowledge. I think its knowing what their core audience really cares about and being more interested in that than crafting a story.
Which I get too, but Im definitely going to complain about it so that maybe more things that appeal to me might get made.
