I found this quote interesting,

“The nanos are taking over him, and these primal impulses are bubbling up within him. From his point of view, it’s explicable,” Watkins says. “It doesn’t mean we have to like it, but he’s acting out of some combination of self-defense, love and a weird obsession. He’s just gone at that point.”

My immediate reaction is that the film didn't really show the nanos taking over. But I guess they do reattach his body parts/blood automatically. They do take over and cover his eyes.

I wonder if you could have had a moment on the red carpet where the paparazzi say things like, "Is he taller?" or "How did he get his hair like that?" or anything to do with vanity in that scene.

I think a few more little moments where he's learning that his emotional state is helping him control the bots. I know he ultimately learns from Caitlyn, but some more clear hints might have been nice.
