Craig Mazin who developed Chernobyl is also the showrunner for The Last of Us - season 2 is out next year. He'd be perfect for an East Germany based spy series with a tone similar to Chernobyl combined with The Lives of Others
That scene in Chernobyl breaking down the explosion is one of my favorite scenes of all time. It's a subject matter that is very specific, they covered in enough detail to be legit, but glossed over enough to not loose the audience. Something that a producer would want in a TV show and an attorney presenting a case. Of course all of the underlying "In Soviet Russia..." type references of the State does no wrong while having it shoved in their face were priceless to me as well.
