Some things I don't really get about it. These may be stupidest observations/queries but I will have to watch it again as I was being constantly distracted whilst watching.
Is the world they are in is actually physically real? I was under the impression before it started that they were in a virtual reality of sorts. Like a matrix sort of thing.
It's a physically real place, which did make me curious what happens if a visitor falls off a cliff or something but I imagine there's safety related paperwork they have to sign.
Are the newcomers just dressed up and sent to the location to start their day and do as they wish?
That seems to be the case, I assume there's some kind of training done beforehand to ride horses and shoot guns but that's just a guess.
Ed Harris says he's been there for 30 years, is his day restarted on a daily basis?
The impression I got was that he'd been visiting for 30 years, not that he had actually been there for 30 years. It wasn't totally clear if events only last a day or not as the hosts we followed had a tendency to die on that first day, it's possible that things are supposed to run for a week or so before ending.
Are the management people and the programming team on site?
Is this like a Truman show sort of world where is boxed in? Surely the landscape is too vast for that to be the case.
It seems like it's a boxed in world (the limits were shown in the control room) that covers a pretty vast area, which is plausible I guess considering there are locations in America that are pretty huge and desolate. It seems the crew are somewhere nearby, the town seems quite close to the perimeter of the site so presumably it's located around there.
