Droped it. Something wasn't convincing for me. The themes were dark but the movie didn't deliver them good enough to convince me... maybe if I were 20, 30 years younger.
What Sun Woo did to get her son... It was wrong. However it was a matter of life and death for her. She needed the son more than Tae Oh at that time but the son could't see or feel that so she had to force the outcome. The time her actions have gotten her with her son gave her a chance to find a new start. And she has to pay for her actions latter on and it is also right that she does. However by the time she will allready be able to pay the price. She will be strong enough.
