Plot twists built on other plot twists and the constant killing with seemingly no explanation.

Did I like the movie? Yes. At first it was hard to get into, but as more and more people died, and all the explanations given or guessed by me turned out to be false, I started to enjoy it more. Why are people dying around Ga In? Why is everyone trying to kill her? The movie presents few answers, but at the same time dismantles them with new information. Plot wise, even though fairly simple, will keep you interested. It dives into the dark topic of who and for what reasons could kill and how much of the external factors are needed to convince them to murder.

The best performance award in the movie goes to Lee Kan Hee for playing Ga In's mother. That once kitchen scene truly impressed me.

What else did I like? Some pictures created were amazing and shocking. Especially two scenes: the hospital scene from the beginning and Ga In's dream with the ceiling involved (once you watch it, you will know).

Any warnings? Some scenes are graphic, blood is more than present more than once. It's also an older movie, so expecting extremely high production quality would be a mistake.
