Don't Cry, Mommy (2012)

In both movie the main character seek revenge after their loved ones get raped

They are both about a single parent who seeks revenge on their daughter's rapists. I find broken better than don't cry mommy. But they are both good movies.

Both are Revenge themed movies in which the main lead takes it upon themselves to hunt down the murderer after a loved one dies.

Same revenge stuff. If you liked one, you might like the other one too.

The last case in Juvenile Justice mirrors the plot of Don't cry mummy.
Both will have you crying buckets
Both reflect on how the system treats Juvenile offenders

Same kind of plot: a person seeking revenge for a girl being raped.

both based on Miryang case and have a similar vibe although han gong ju is better

They both deal with mothers seeking revenge after their daughters get raped..

In both a parent take revenge on the persons who assaulted their daughter because the law and police are powerless.

Both have a similar story about a divorcee mother who are raising there teenage daughters. Until they get raped by boys/men who tricked them. Their only way for justice is to take the crime into their own hands.

They both centre around suicide and injustice towards rape victims, they also share the social aspects of school girls and vulnerabilities towards sexual harassment and rape, the other main character is their single parent whom is ready to pay revenge to the criminals who led their children to a spiral of unhappiness and depression
