The Witch: Part 1. The Subversion (2018)

They are both verry gore and have a strong female lead. They both are centered around a big organization that locked up kids, looking for the one who escaped . They are somewhat the same show with one where the girl escaped with her friends and formed a family and the other escaped alone and fighting with herself. I really think they could be in the same universe.

Both main characters kill villains mercilessly, but the witch is science-fiction based and a more structured plot.

Both feature:
- young female leads who are trying to survive against enemies who are trying to kill them
-dark killer themes
-kick ass female action
-strong female empowerment

The stories are completely different, but the message/theme is somewhat similar

There is not much to say why they are similar, more where they are different.

It feels like Revenge Girl is a Chinese remake with a sprinkle of dystopian future on top, and more wuxia style of fights with less dead bodies than in 'The Witch'

Similar vibe, plot line, even character relationships. Both deal with inhumanly strong female main characters (gene manipulated) on a journey of discovering the past/truth.
