I recently watched Wake Wood for the first time, and I was quite struck by the rough-hewn wooden items used by the villagers.
The rhythm sticks and rattling drums played during the ritualistic processions:
The fascinating abacuses used for some sort of supernatural consultation:
And the devices used to control the revenants and ease their transition back to the beyond:
I enjoyed the tangibility of these seemingly ancient objects imbued with occult power. And I liked that there was no attempt at explanation of how they might work, leaving it to the viewer's imagination.
