I used to watch Ancient Aliens a lot...
What I find puzzling is all those shows about islands with SECRETS. I've never watched any of them. And then there's also Skinwalker Ranch, which I think is not on an island, but may as well be. They've all been on for I don't know how many seasons. shouldn't they have run out of SECRETS?
I gather the actors all pretend to take the premise--which, I suppose, involves finding SECRETS on islands or ranches--seriously. I wonder if they spend their downtime on set drinking beer and laughing their heads off.
