My wife will watch the IFE movies, I never do. I read on a Kobo most of the flight, with noise canceling headphones and ambient music playing. Long haul I will watch a movie or a show, but it’s always preloaded on my iPad. iPad is good too, as I can use my good headphones with it and no wires.
The only exception is when I watch the movie for a while on the guys seat ahead of me. 😁.
My wife watched the entire Godfather trilogy on a IST-SFO flight. (On the IFE)
