Long routine briefings on familiar departures/arrivals fit the definition of too many university lectures: "a system whereby the notes of the lecturer pass into the notebook of the student without passing through the minds of either".
In some airlines you could cause great alarm by answering the routine "Any questions?" with "Yes!"
For familiar airports it's much better to ask a question or try, "Let's run through together our actions in the event of an engine failure on take off."
Very important in a routine operation is "What's different to-day?"
(I've had people run through a boring let-down brief at a Canary island on a gin-clear day without mentioning the strong possibility of wind-shear).
