Don't disagree there are issues, but I don't think the tone is one of them. LOTS of people take shock like this in different ways. We are very used to the extreme expressiveness and pacing of TV and movie actors.
Many real people in shock sound overly subdued. They are processing what they just saw / heard, and don't have to worry about expediting into the next scene, keeping people entertained.
