Mark Levin's New TV Show: Who Is The Real Levin?

Mark Levin is a loud bombastic and intelligent national conservative radio talk show host.
He is also an accomplished lawyer and started his own online TV channel, CRTV.
On Sunday night he debuted on Fox News with the show "Life Liberty and Levin".
He had Walter Williams, a black libertarian, a noted and prolific author and intellectual.
As far as content goes, the show was very good.
But when you have intellectuals as the guest and host, well, the staying awake factor was pretty low.
As a listener to Levin's show, it is hard to listen where it is loud, rude at times and fast paced and then to watch his TV which is much slower, measured and not funny.
So, who is the real Mark Levin? The loud, funny and bombastic Mark Levin or the quiet, measured and serious Mark Levin?
My guess is the latter.
