No spoilers here!
The whole story is a little chaotic, but the ending helps make up for it and leaves it open for a season 2.
Different video styling, lighting and the integration of supernatural beings that are appear realistic, but are CGI. I could go on about the religious aspect of it, or even what you might do for another human, But watch it yourself and make up your own mind.
All in all, it makes you question your beliefs and just shakes things around.
Just watch the whole thing, it just makes sense. Also, it is 2.24am as I am writing this.
Hope this helps
