Might be an anecdote, but I've noticed several friends and family unable to focus on a movie and lately even on a tv show without pulling their phones every few minutes.
I mean, "want to" is one thing, but the numbers show what they end up doing. Instagram and TikTok, like video games as someone else mentioned, have taken a significant share of the "entertainment hours" budget. I feel like the impact of the low-to-no-budget content creator is undeniable (this traces back to ebaumsworld and early YouTube, it was just internet dorks then, now it's been industrialized. Gen Z probably wholeheartedly prefers this type of content).
My point was that content creation has been democratized -- unfunded individuals can now compete -- not that making traditional Hollywood-style movies has been. It's gone so far they've been phased out, the entire premise is largely untenable at this point. That specific sector was actually somewhat more democratized in the late stages of the heyday, when a Hollywood movie called Dude, Where's My Car was made, and indie films did flourish because the industry was healthy enough to support them.
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.
