> Gen Z probably wholeheartedly prefers this type of content

I think it's virtually all demographics below 70.

My 60/70 years old family are all too distracted by the phones to watch a movie, and so are millenial friends.

True but I think a lot of them would be in the "I totally want to watch feature films" camp. By wholeheartedly I meant that the kids don't even have that pretense.
