I can sit on a lot of exposition about the Norden bombsight but I would agree with the show runners it was a good call not to do that for a general audience.Apple is going to Apple. They want to gin up interest in their show.
I watched a couple of episodes and rate it just below the Pacific Band of Brothers. That doesn't make it bad, but also doesn't make super compelling. There were so many interesting aspects of the 8th AF - The Masters of the Air book was a page turner - but much of that isn't covered in the show. So blame the show runners? I mean, how did a bicycle race make it, but more description on the bomb sight not?
They do give some tips about it on some episodes just like that gave some tips on if perhaps all this sacrifice was worth it (some episodes to go).
In the end the script perhaps isn't the best. The fly/bar routine is overused among other things already said by others.
And soon enough just by the intro the show will do a 180 turn.
In the Pacific the Sledge part was stronger (IMHO). Perhaps that can happen here too.
I also had some trouble with the voices but as I'm not a native English speaker I believed that to be the problem despite usually not needing subtitles.
