And all kinds of stories were presented in theatrical films. Then TV came along and some great stories were being told on the small screen rather than the big one. The disadvantage of course was that you had to have commercial breaks.
Then came cable and channels like HBO started producing original content, and much of it is very good.
But I think movie theaters may die out because their business model just doesn't work anymore. They are generally only busy on the weekends. It's just so easy to watch HBO (and others) or "Netflix and chill". There is some innovation out there newer theaters rarely have screens with more than 150 seats. There's a Cinemark near me where some of the screens only have 50 seats! But with digital projection they can show one film on multiple screens with the flip of a switch.
I do think they will still make "movies for grownups" but many of them will be viewed on your TV rather than a theater. But those are the films that don't lose much by viewing them on a smaller screen and you can get a 55" flat screen for under $500! The thing is between theaters, cable, streaming and VOD, there is more demand for original content than ever. You might have to hunt fir it a little more, but it's out there. An indie I recommend right now is "Blame".
