I have seen part 1 and 2 or so.
What I learned from it is that hollywood is pure satanic. Watching the video leaves severe negative psychich impressions on your mind and spirit because it is aimed to do so.
Naturally, youngsters will call other youngsters who would refuse to watch it sissy's, acting like gatekeepers to keep the flock of sheep in it's place.
I do not believe in satan, but satanic conciousness and spirits are very much real. They are extreme knowledgeable at putting satanic 'directions' in music, audio and video's. You shouldn't watch the movies since it has no benefit, is unrealistic and will only bring you down. All this is the exact aim of the 'saw' hype and unfortunately it is selling well.
