Well, back in my day it was totally normal for a plane to show one movie for everyone. There used to be one screen at the front of each aisle, and sometimes a few more that came down from the ceiling, but this whole personal entertainment system where you get to choose what you want to watch, is brand new relatively speaking. You used to get on the plane, find out what movie they’re playing, and choose whether or not to plug in headphones.
I agree though, if the system is broken, just leave it off.
Greetings, fellow geezer! The difference is that those movies were easy to ignore. If it's on the screen right before your eyes it's going to be annoying.
