It is amazing though, with the descriptions and what people said here, when I was actually WATCHING the episodes last night (One and Two so far), I felt like I had watched it originally. I don't remember if anyone else said anything about these things:
All the times we see people in mirrors. Instead of seeing them straight on, we see them first in a mirror.
Also, the call letters of Brother Justin's broadcasts, KZAK. Could this be a reference to Kazakhstan, which is part of Russia? We know Justin and Iris are Russians, but is that where they might be from?
The radio in the prison - when the guard turns to look at it, it looks like the face of a wild animal about to pounce. That was a little creepy.
The virgin and child statue - the child turns to look at Ben, and Mary's eyes look like they have been scratched out. When the nun calls him, it turns out to be a hallucination, but what is the statue trying to tell Ben? If anything?
