I was in high school in the early 00s, and going to the movies was such a big part of my life. Now, I never even know what's out.
I suspect life stage is a factor, but it does feel like there are many classes of entertainment (cinema and standup come to mind) that don't resonate like they used to.
Back in the day everyone was watching the same thing.
The choices for entertainment were limited to whatever was showing in movie theatres, whatever was on TV and whatever record stores were selling.
