Does Obama ever get excited about anything?

The description being given by most commentators of Obama’s demeanor in delivering last night’s speech is “cool.” Cool? He could have used the same tone to give a weather report. Showing some emotion is not the same as losing control. Joe Biden could have done a better job with the speech (provided he stayed on script). Heck, even with my nasal New York accent, I could have done a better job. Does anyone else feel the same way? I kept waiting for the president to show a some animation.
