Bloody, gore, sick, violent torture movie. A classic for it genre.
This movie is not exactly horror in the way most people understand it, neither paranormal and there's no exorcism.
The plot is simple. Nothing deep. Almost no story for me. No backstory and no explanation how everything started and for what reason it is happening. Maybe there is something with first 2 parts, but unfortunately I haven't watched them
Just a bunch of people messing with the wrong ghost(s) for a greater good and the ghost(s) brought terrible vengeance on them afterwards.
The movie is relatively short with nothing happening during the first 1/3, really, nothing. Then everything "escalated quickly". There are sick ways of getting people killed/tortured to death, although some are not so realistic. When a scorpion bites you, you don't explode. *Phisics*. Explicit violence most of the time.
The end was kind of unexpected, like unfinished, cut. Then there was some backstory for the backstory of the movie. The plot twist at the end is great.
