Honestly? I'd like to see the ramifications of ignoring the real world as it goes to shit with VR explored more seriously, the first book kind of hints that it wants to tackle this, but never really does, this is what people don't get about the book though, it's not just a nostalgia trip, it's a nostalgia trip set against the backdrop of a dying world, this is also something the movie barely acknowledges at all and one reason why it's inferior to the book.
We don't need a full on Last Jedi style subversion of expectations but an exploration of just where humanity might be going has potential to be interesting.
This is what's funny is in one way RPO's depiction of a future world where geek culture isn't simply people having constant political pissing contests makes it incredibly dated, as much a retro future as anything from the cover of a 1950s science fiction magazine.
It's also funny how quickly it became dated considering only the following year was when Sarkessian launched her Tropes vs Women Kickstarter thus firing the first shot in this Forever War.
But in another way the novel was incredibly prescient as nobody was really talking about VR back in 2011, that was before the Oculus Rift Kickstarter and it's amazing how far VR has come in the almost decade since the novel.
