Revenge against God for the crime of Being.
That's a very apt and subtle choice of phrasing that carefully avoids propping up Star Trek as a whole as exemplary at subtlety. X ] I don't think subtlety per se is actually what makes it fly or not, though. Or if it is, it's subtlety of craft, not subtlety of message. TOS had some very good and unsubtle episodes and TNG had some very milktoast veiled commentary that managed to ring false both to the real world and to the fiction. And Star Trek is okay with being didactic, that's a quality of the series that we're all aware of and that a lot of its stronger merits depend on. But like, does the story actually back up the message they're trying to present, does the show handle the balance between representing real-life analogues while being true to the situation actually presented in the narrative, does it handle serious subjects respectfully, is there an appreciation of complexity, etc., all that makes the difference. It's a matter of insight and of craft. That's different from the kind of subtlety that says you could have missed that a thematic element was there, more that it does right by the story enough that you could pretend it didn't have that resonance and it still more or less works.Star Trek has always had politics, but the difference between the writers of various iterations is the level of subtlety with which they weave it into their stories.
I hope I'm not spoiling anything to say that SNW has touched on politically topical themes once or twice thus far but I think they've been very carefully handled to respect both the real groups of people and the fictional characters in their presentation.
