I am getting a little tired of this "most pax take no notice of the briefing" stuff
I sympathise entirely - maybe the airlines should introduce a currency requirement. At check in you could state when you last had the brief and what amendment state the brief was at, and then be exempt from paying attention.
It could probably go hand in hand with a similar drive in the cockpit:-
Capt: "this will be a Grice 3 C departure..."
F/O: "Yawn...yeah yeah, I heard that one yesterday, and last week."
Capt: "ah, ok I'll not bother briefing the take off then."
I'm sure the pax would be delighted to hear that.....
