Revenant is a horror themed drama, while Save me was about Cults. Yet when I watched revenant it greatly reminded me of Save me. In revenant the main characters were trying to escape from the grasps of the Evil spirit or "Akkwi" while in Save me the main characters were trying to escape from the grasps of the Cult leader. We see dark themes like "sui**de" and "mur**er" in both of these dramas. In Revenant, we see Kim Tae ri's character was troubled by life and was on the edge of it all when the evil spirit possesses her. In save me. Seo Yeji's charcater and her family were facing multiple difficulties and tragedies before they were lured into the cult. Both the dramas showed the evil deeds of rich people. While watching both of these dramas I was absolutely terrified of what will happen next. These dramas give the same vibe. If you enjoyed watching Revenant then you will probably also enjoy watching Save me.
