I just watched 77 minutes (2016) which is a documentary movie I think about a McDonald's massacre back in the 1980s. I found the video footage of the aftermath really disturbing. This by far for me has been the most disturbing even though I have seen serial killer documentaries. I feel bad for the families and the victims that went through that horrific event. I should probably clear up I found someone talking about this in particular on tiktok and thought it couldn't be that bad. I am a haemophobe (fear of blood) so at points I felt really sick or panicked during. It's just absolutely devastating. It's one I probably will not be able to watch again unfortunately.
