Ben Affleck is a Genius in 'The Accountant'

This is a really vague trailer, but I can tell you right now that I will never buy Ben Affleck as a math genius or whatever it is he's supposed to be here. He really has two notes as an actor- comedic, which is the thing he can actually do well (see Dazed and Confused, Shakespeare in Love or even Good Will Hunting) and the other note...well, I'm just gonna call it vacant. He stares blankly a lot in dramatic movies. This looks like another one of those.
