People look at this from the stand point of NOW... the
early religious building were built to overwhelm and
scare people so as to control them...
early religious structure were not for the people to ENTER... they were places
where the priest visited to SERVE THE GODS THAT LIVE OR VISITED THERE... AND GET MESSAGES FROM THE SECRET UNSEEN GODS to convey to the people... this goes back even before the great Egyptian temples and gods... way way back into prehistory.
There are jump -
scares that are more than just
scares, as you'd imagine in a wilderness
where the flora and fauna have mutated like cancer cells (a metaphor made plain in a classroom scene
early in the film).
