I always watch these short documentaries with a great deal of interest because it typically rouses enough curiosity in me to do my own research afterwards.
Such was this case.
I also found the documentary to be non-conclusive,though one might gather, from the title, that it is in the negative.
The most glaring error, however,in material is that the narrator and documentary has a grim, misty picture of an "unmarked" gravesite or obscure one at best, while after my research, discovered,though banished to Switzerland, Mesmer had a brisk practice there until his death.
Additionally, Germany has erected a huge sculpture honoring him in Meersburg, Germany where he died.
Sensationalistic claims not based in fact are a waste of time for me,although, as I said before the initial appeal of most documentaries myself is prompting me to do my own research.
