At times, it feels a bit like a Hallmark/Disney Family movie and can feel a bit "over-acted" (perhaps the latter is a cultural difference), but overall it's an engaging story that the actors do well to have you feel. I was a bit disappointed that the Jang Min-Hwan character (the prison warden, played by Jung Jin-Young) wasn't more fully developed, as it appeared that the story there would have been a good replacement for much of the so-so story told from within the walls of the prison. It receives high marks from me due to the powerful emotions that it invokes and its ability to intersperse comedy into a story that would otherwise be difficult to find humor in.
cried a river watching this :'(
Wow a beautiful movie, I almost lost my grip but I lost it from the inside :).
