One thing about movies depicting nature at its best is that it tends to be confusing, bizarre and somewhat unique. It's showing the power of tree roots connecting with each other miles away, unconsciously drawing people with like mind or should I say "same brain wave-length" together- congregating, communicating and embracing mother earth's true spirit. It's scary because nature's soul, being invisible to human, is having a life of its own and not keen to have human partake into that.
It's a nice movie to keep you mulling over mushroom spores, moss, trees and dews.
