Save me portrays how certain religious leaders or groups go to any extent to manipulate and abuse people. To think there are people who are as gullible as Sang-mi's dad and would believe and act on anything a priest says even at the detriment of their loved ones is scary. The dtama really captured hurtful and unimaginable things done in the name of religion.
However, I liked the fact that there was light at the end of the tunnel for Sang-mi. She was able to break free (her will and the 4 boys).
