There’s not a lot of accounting being done in “The Accountant 2.” In Gavin’s O’Connor’s 2016 action-thriller “The Accountant,” neurodivergent number-cruncher Christian Wolff (Ben Affleck) was equally likely to choose a spreadsheet or a gun when balancing the metaphorical books.

Ben Affleck ’s Christian Wolff is like if A Beautiful Mind ’s John Nash moonlit as Batman. In The Accountant 2, autism remains his superpower, granting him the ability to both crunch numbers with extraordinary speed and accuracy and to assassinate bad guys with peerless lethality.
