The entirety of this movie was so painful to watch, and the fact that it is based on truth makes it much worse. The young girls did extremely well at portraying their characters and the pain they went through. I only cried once during this movie, and it was when 'Arirang' started playing at the end and all the spirits, in the form of butterflies, flew home. At that point I was bawling my eyes out. This movie is very educational and a must-watch, but take some time before watching it to prepare yourself. I don't think I will be watching this again time soon.
