South Korea also has a cinema scene. I once saw a Korean horror and it was unlike anything I saw before. Like, really weird. But it had nothing to do with spy drama.

A lot of spy drama or action from the Cold War era is very over the top and/or propagandist/fear mongering. Drama is dramatized, but can easily be regarded as overdramatized, bending the truth too much in the process. At such point, a good documentary on the subject is probably preferred. The faith I have in a country like China or North Korea being authentic on such matters in documentary is near zero, and thus I assume their drama on the matter will equal the low effort American cinema we saw previous century.

That a band like Laibach was allowed to play in North Korea is very much telling to me.
