I watched it last week.
Overall it was a good film, it does highlight concerns of certain secret societies partaking in "satanic" rituals, and covers the likes of Pike and Crowley..
As much as I personally don't want to believe in demonic "spirits", it certainly raises a few unanswered questions and concerns, there's got to be some form of truth in there, otherwise these men would not have dedicated so much of their lives into the occult..
I personally have witnessed a black flying saucer, and 2 silver orbs in daylight, from those experiences, i'm more inclined to say "alien" of some sort, certainly not demonic..
So, no, it has yet to convince me UFO's are demonic,
That still leaves the question, what are these "Demonic" things others have encountered?
Im more inclined to believe they are beings of a different density/dimension, that we dont yet understand, so class them as demonic, religious people especially are more inclined to think they are "Evil"..
