Just came back from #Horizon ... No significant spoilers ...
I can see why this movie is inaccessible. The central character is not a person. It's a place, a small town called Horizon.
Someone (we don't know who) is printing up flyers promoting a utopia Western town called Horizon. Why? We don't know.
This film, "Chapter I," is a series of tales related to Horizon. Some happen in Horizon. Some don't. But all these tales eventually link to Horizon. (1/x)
