What I really loved about this portrayal of Mr. Terrific was that yes he is the smartest man there. But he is so expressive. So many smart characters have to act like their above emotion and reacting. But no he's getting mad because he knows he's too smart to be dealing with this shit
"You brought the damn dog????"
*shoves guys face out of the way with his entire hand*
A lot of geniuses on shows and movies become detached because their so much better than everyone else. But Mr. Terrific is very much present and kind of always pissed about that. He's human and caring enough to not just Dr. Manhattan his way out.
He gets the job done but he will also tell you "Hurry your ass up!!!"
