It doesn't really matter if it's scripted. It's how it's delivered. Of course it's going to be scripted. You don't just create a show out of thin air.
To do live TV week in week out is a talent. That's why it's often the same people doing it.
I just don't understand your reasoning that their relationship is genuine when there is no spontaneity to those moments, its scripted to every letter - it's like saying two actors have good chemistry in a film.

well played sir!
