While the filmmakers of the documentary below see no harm in it, I don't advocate celebrating Halloween or participating in these practices because of where they come from. However, I appreciated the thorough history they showed in this film about how the celebrations that take place on this day began...as well as how they evolved into what they are today, so I thought it was worth sharing.
The video has 5 parts, but the first 3-4 are the most informative about the actual history of why the day came to be celebrated.
