Why would I watch someone else's AI content when I can watch my own with about the same work? It probably takes longer to pick something on Netflix than to shout at my TV to show me some auto-generated on the fly show about whatever I'm feeling like watching right now. Can even be building upon itself "show me yesterday's show but in space and give it some new twists that I don't expect".
The conversation then becomes more about the platform than about specific content.
Similar to a game; for many games players aren't intended to have exactly the same experience but there are still common things about the game platform to discuss.
I think it would be pretty cool to have a partially AI generated plot, it would be exciting to discuss what you got in the AI lottery with someone else who had also watched the show. Something like: [set plot point] [random catastrophic event] [set plot point] [etc]. "1 character must die in some meaningful way" turns to "omg, which one was killed when you watched? Adam got eaten by the giant spiders in mine" "oh man, Sarah tried to set a spider on fire in mine, but she ended up getting herself". A la https://en.wikipedia.org/wiki/Until_Dawn
