Halloween // Favorite documentaries to watch around Halloween?

I was listening to a podcast the other day about the history of Halloween and a lot of the stuff in it, I wasn't aware of so that made me wonder what documentaries are out there about Halloween so I was wondering if there are any documentaries that you guys turn to or enjoy watching around Halloween? I saw one from History on YouTube that talks about the history of vampires, one that covers the history of voodoo and I plan on watching those but yeah, I was just curious about what kind of documentaries you guys enjoy watching around Halloween. Since I don't have many on my list, I'm definitely open to suggestions!
