Well, it did reach for "I double checked it, I'm totally sure now" language.
From the perspective of trying to convince the top brass that they are making good progress towards creating an artificial psychopath - not just an artificial human - it's pretty good.
Having worked in computer graphics myself, it is spot on that this shit is uncontrollable.
I think the reason is fundamental - if you could control it more you would put it too far from any of the training samples.
That being said video enhancements along the lines of applying this as a filter to 3d rendered CGI or another video, that could (to some extent) work. I think the perception of realism will fade as it gets more familiar - it is pretty bad at lighting, but in a new way.
