Do not watch the movie. Despite the fact that we will be showing the trailer this segment, it is incredibly important that you avoid this movie at all costs.
That being said, you should read the book. The Serpent and the Rainbow is the story of Wade Davis’ trip to Haiti, his introduction to the Voodoo cults of the area and his search for the secrets of the Haitian Zombie. It’s at times self-congratulatory, there are some criticisms as to its validity as research and it occasionally drafts from the point but it is still a fantastic piece of source material for anyone interested in the history behind Haitian Zombie folk lore.
You will also get a feeling for some of the psychological and sociological drivers that may be the cause of the prevalence of Zombies in Haitian culture.
It’s a fascinating read and a perfect addition to the book shelf of anyone who wants to survive the Zombie Apocalypse.
