Most stupid & confusing movie EVER

Rating: 1/10 (16 September 2019)

What is this movie about? It's just rambling through sound and special effects from one nonsense to another....
Spiderhead, drools, blood oozing from walls, vomit into mouth, guy in burlap sack chained to water pipe, sound effects, orchestra music, echo chamber, golum lady, indian tribe rituals, aliens, deep well, ritual, pagan, orbs, is this a scifi outer space or cultish sacrifices or hell on earth or the Thing or three doors or tentacles or flashbacks or guilt or special effects or blood flood or true love saves the day, everybody has guilt? more aliens? Or just special effects? What? What? What?
This is the most time I've ever wasted in my life.
