The thing that I have learned from this movie is that you don't really need many actors so It would be a good movie .

Acting was absolutely superb. Very believable performances from everyone involved and amazing work to show changes of the emotional and psychological states in the main characters. Jeon joon seo & Park shin hye played a brilliant role here. Young sook's laugh still give me chills! She played a real villian man!! Hats off to her character.

There is one thing I noticed, The cliffhanger ending that is supposed to shock us but ultimately doesn't fulfill any form of surprise or dread. No, that ending doesn't work at all. Let's just say it made no sense that our villain, wouldn't be found after what happened to her. I know cliffhangers are fun, but at least make them believable.

I liked how the relationship of mom-daughter changed in the end, when from the start Seo-yon towards her mom wasn't in good terms at all, maybe she thought her mom was kinda selfish of herself [doing her nails and such to make beautiful] but the twist of the plot showed that a mother will do everything just to protect and save her child no matter what. Seeing Seo-yon smiles at the end proved her how her mother loves her very much.

Overall, a very well done film that, throughout has you at the edge of your seat
