Brief what's unique to the departure/arrival as appropraite.
E.g. lets say there is an emergency turn to follow in the event of engine failure after V1. In my book to brief but omit to mention the ET is about 2 out of 10 - say nothing but mention the ET is about 8 out of 10.
If you drone on for hours about stuff that is "standard" then fellow crew members just switch off. In certain instances it is quite appropriate to say "Standard Brief for RW 24L at MAN..etc" but at other times a more comprehensive brief would be necessary.
