Beware => spoilers

The plot and storyline of this movie are pretty simple, basic but efficient : an older sister looking for her little sister after she disappeared. And she decides to take revenge.

Lee Si Young well portrays a badass FL (similar character one as in Sweet Home). Her acting skills in movies of this genre (action/fighting) are very good.
The other characters are not really important. Not that I want to minimize the job done by the other actors but I think support roles could be portrayed by any other actors, I doesn’t matter. This movie was only done for Lee Si Young.

I give this movie a good rate because of badass FL, because of the revenge taking story and also because of action scenes. But not high rate because I admit I’ve felt pretty uncomfortable about everything the young sister went through… I’m sure storyline could have been the same even if the bully/abuse level had been lower.

Good movie but no rewatch value for me.
