There is non-violent documentaries like Dr House and another one I saw on Netflix. Its just that ppl like to watch violence so there is more violence documentaries. Its like violent action movies, ppl like to watch them more.
No one will watch non-violent schizophrenia documentaries, ppl find it boring.
You speak french so you can watch “un monde sans fous” (a world without crazy people.)
Another one is happening in a psychiatric hospital named “Saint Anne” in Paris.
Good documentary.
Youtube is your friend
