This movie had me for a while at the beginning, when Li Ronan asked me or we the viewer to memorize an insignia and chant an incantation, which got me thinking, "Is it a real deal?" The viewer who is easily influenced by something might be scared to death when they hear Ronan's request.

When I found out that this film was from Asia, I thought I could relate to what the film would tell, but apparently not, this was like another horror film about people who came to a cult, then ran away while bringing a curse, and had to return to the cult (to what they thought) to end the curse. I'm not too concerned about it, though.

In my opinion, as a Found Footage film, this film has a decent execution, has a few tense moments that make goosebumps and shock, but there are shortcomings, like this film that I don't think has an adequate atmospheric foundation to supply help to make horror sequences feel impactful, relying solely on jumpscare to raise the levels of horror; sometimes this film also has a shot that does not come from Renon's camera and it is annoying.

I heard many who compared this film with The Medium, but honestly I prefer The Medium, which has a relateable material for me who live in Southeast Asia and succeed in providing authentic despair experience.

Instead of The Medium, I remembered Paranormal Activity: Next of Kin while I watch this film. The thing that makes me remember PA:NOK is the characters accompanies a character to go to the village of the character who turns out to be a cult nest; the creature that is worshiped lives in somekind of hole (PA:NOK - bottom of a pit; this film: tunnel); PA:NOK is more open that they use 3rd person POV which in my opinion are more acceptable than giving unclear shots that are not from Renon's camera.

Not bad, especially maybe for those who have never watched this kind of film probably would think this film is very good. That's it. Thanks.
