How scary is Beware Boiúna?

Nobody has rated it yet. Ratings on Scare Scale come from people who've watched the film, and score five kinds of scare out of 10:

Gore
Blood, injuries and body horror shown on screen. Violence that happens off-screen barely counts.
Creepy
Unsettling images, atmosphere and things that feel wrong. Not sudden shocks (Jumpscares) or waiting for something to happen (Suspense).
Jumpscares
Sudden shocks designed to make you jump, usually a fast movement or a loud noise. Not slow-building dread (Suspense).
Suspense
Tension and dread while you wait for something to happen. Not the scare itself when it arrives (Jumpscares or Gore).
Psychological
Horror that gets in your head: paranoia, madness, doubting what's real and ideas that stay with you. Not how a scene looks (Creepy) or feels in the moment (Suspense).
