Sci-fi television writers don't seem to do military stories well without
falling into cliché for some reason. There are a few, mainly the space
operas, but shows like Sherlock, Doctor Who, Buffy, Supernatural,
etc...just tend to do the stereotype.
The Expanse, Farscape, Battle Star Galatica handled these sorts of stories
And yep, I think part of the problem is Mark Gatiss, who is a sloppy writer.
