Nothing or something to lose
A small flame smells kinda burnt, yet fire glows.
It's just a real sign that watching this movie means you're coming into play with the very capable forces.
The main point is there's stuff that can't be explained, and we wonder why not. The fear must be entered into, or at least faced, it would seem. Many are there unwilling to accept having to do with the truth.
Anyway, this is an awesome show if interested how an exorcism is, whether you believe the possessed has anything left inside or not. It's quite a short snapshot of this person's life, it's impossible to decide not having background although the strengths are found in the deep theological snippets.
