It looks like Bruce Wayne / Batman is clearly going to have a different relationship with each member of the Justice League.
This leads me to believe that Justice League’s humor seems more on point than in Batman v.
It not only combined subtle characterization about Batman cutting to the chase with an integral plot point as Allen learns that Bruce Wayne is Batman, but it just looked cool as fudge, too.
