What it might be like, on the cusp of reality For me, this is a kind of "Batman in the real world" tale of a man with a rigid code who takes out those who violate his order, and occasionally, almost against his will, forms attachments he doesn't understand to other humans.
I find all of the principals excellent, but Affleck is a revelation in his ability to commit to the utterly inflexible worldview, and carry it to its inevitable, and borderline insane, ultimate form.
It doesn't have the body count of John Wick, and Christian certainly isn't positively charismatic, though unquestionably terrifying in places, but the mix of math, mayhem and a need for structure make this the closest thing I've seen, if he could kill, to a Batman not confine to comics movies.
