One of the most beautiful psychological thriller-horror that I have ever seen. I was at the edge of my seat for the whole 2.5 hours. it has a great atmosphere which can lead you to feel all those pains that the main character "Dani" is suffering. up to me, the most important thing about Dani was its character arc. I mean changing her personality from a girl with separation anxiety to the one who sacrifices her lover for revenge.
furthermore, its cinematography was eye-catching and lets to subtilize the darkness which exists throughout the story.
