It's not simply that people of my generation are getting nostalgic for the tropes and indications of our childhoods. No, of course not!
What's happening is that we're doing the important historical work of sifting. In every cultural moment there is "good" and "bad" ... that which is well made within the context and rules of the genre, and that which is not (which is mere tired copyings of earlier styles or mere pastiche of the signifiers of the genre itself.)
Our job, now, is to begin the process of analysis. To identify what will stand for us in futurity and what later generations can safely forget.
