An enigmatic amalgamete

Rating: 2/10 (25 May 2019)

1.Because of the antagonists of this movie,the "Tethered",are exact living copies of their host with exactly same appearance and character from their host,I can not figure out which is the copy and which is the host, especially in the later part of the movie when the secret basement was shown and during the part where the protagonist killed her copy and her memory of year 1986.
2.The plot and meaning of this movie is still a mystery;I don't know what the "Tethered" in red holding hands together and police choppers flying above them in the ending means.Can't the police on the choppers just shoot them directly?!
As a summary, this movie is a horror movie because it featured blood and gore,killing and antagonists wearing dark-colored cape,but this movie is also not a horror movie because the "Tethered" is still a mystery.
The worst thing is,this movie is with a nasty long opening music with enigmatic, Shamanism-like lyrics.
I still can not understand this enigmatic amalgamate.Maybe the director played extremely enigmatic games like Yume Nikki before, I think.
