There's a part of me that wants to say part of the problem is just that stories about democracy are so complex and so inherently collective -- it's easy to come up with a simple, satisfying, 1.5 hour plotline about a monarch who can just Do All the Things, we have all those useful one-person-head-of-state tropes to draw on and then all the interesting political complexity we get in something like Black Panther feels like going above and beyond, jumping well past the goalposts.

Whereas to tell a story about democracy, you need to set up all kinds of institutions and protocols and the collisions of a whole lot of significant personalities and plenty of in-story time for everyone to, i.e., sit down and read and react to a several hundred page legal document. Which I think you can do! I haven't seen The West Wing but everybody seems to think that did it! And, personally, I love well-done fantasy and sci-fi about communities and complex organisms -- but jeez, it's hard to build that in an hour and a half. And even harder when your premise is ... bad. (Sorry, Civil War.)
