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
