The glances to the camera were more jarring to me. It looks like Michael in The Office.
What reviewers have noted is that they're often just not necessary re. the machinations -- that we already knew what was going on; or that they don't reveal more about the character than we'd have gleaned by watching his actions.
OTOH -- we don't always know ourselves accurately and perhaps the writers intend this to be true for Francis. Maybe we are supposed to be hearing Frank as he views himself, but not as how he objectively is (if such a thing exists). He isn't the perfect manipulator. People surprise and betray him and he screws up on CNN (which, like Apple, must have paid some pretty product placement pennies).
