I first saw this on Sci Fi and regrettably took it seriously. I found what the filmmaker came up with interesting but farfetched.
I did, however, really enjoy watching the events play out. Even as a work of fiction and a mockumentary it holds up, keeping you on edge.
But thing that most took me in was just how merciless the filmmaker in it was. He uncovers deep secrets about Night's past, things that he had no business digging up. Night's reluctance to discuss his drowning would've been understandable given how traumatizing it would've been. On top of that, he put it on national television!
What truly interested me was waiting to see how far he would go for the sake of the film.
The film left me wanting answers but feeling guilty for doing so. Is it worth damaging a man's emotional stability to study the nature of the universe? In this I would've said no, but I enjoyed confronting the issue via a film that takes the opposition.
