I re-watched Chappie recently. I'd already read someone say that The Creator gave them Elysium vibes, and then realized - there's a fair bit of Chappie in The Creator too. Add that to the fact that Rogue One was supposed to 'the District 9 of Star Wars', and it suggests that Edwards' strange goal is to be Britain's version of Neill Blomkamp.
He's already tried to re-invent VFX-led film-making once - Monsters looks like a 10M, but it was made for about half a million. The people involved in that film thought it would change the industry. It didn't, because there's more things going on that balloon blockbuster budgets up, until they all cost around 200M.
As for The Creator, he may have saved 120M from the production budget, but a few million spent on pre-production script development was what it really needed.
