I think this is kind of my point -- there's no way to develop that level of nuance in a movie. The options are to take way more time (see Silo), to do a crappy job (see... almost every 2 - 3 hour movie), or to instead change the goal: Don't have the viewer "develop… a deep understanding", but down-select to those viewers who already respect the work and have that deep understanding, and instead focus on showing them the society and its norms. Do what movies are great at -- make a story come to life -- and make the viewer/reader do the work of knowing the background, knowing what they're seeing, knowing what's important.
