It seems like the movie Trachtenberg was going for here was way too risky and way too ambitious for a studio to green-light it normally. But if he can do that on a fraction of budget. As animation. And not a budget, something like Pixar uses for their ultra-realistic stuff and fluent motion. But on a fraction of that. He can use the trend of animating on-twos and making everything painterly, to cut all of the corners necessary to make this insane movie with the small amount of money that he is given.
