Some time ago I spend quite a bit of time on international flights in the back, have about 350 Atlantic crossings. Regardless of who does the translation, nothing is worse than hearing a PA speech multiple times, especially when (back then) the sound would stop but the movie would keep rolling. About a 150 were in first class. Never ever have I seen a passenger listen enthusiastically. Also did corporate for almost a decade. Non of the frequent fliers were interested in anything I had to say, other than "we are on time for departure, should be there on time too".
I am sure there is confirmation bias on both sides, you get thanked for the speech by people who like it, the people who don't probably can't be bothered to say anything. I didn't like it, so I am predisposed to see other people sigh and look annoyed. Not attacking you personally, just MY view as a frequent flier.
