Honestly speaking, I don’t even think the story was bad. the directing though, missed a lot of basic elements.

The scenes simply do not transition in a smooth way. Everything feels so out of place. Random private naked yoga classes turned into kamasutra scenes, a random detective story, which technically makes sense (people are dying after all), but never matches well with the main story. It honestly felt like they stitched scenes together without actually taking into consideration if they create a cohesive picture and explain the story well.

By the end of the movie they present one too many twists so rather than an interesting (though slightly overused) turn of events, it all becomes confusing.

The acting was bad. Lee Chae Young easily did the best, but all the rest of the cast was questionable at best. Felt like the actresses were cast for their bodies and not their acting skills.

Overall, skip, don’t bother watching.
