I know how difficult it is to lose a loved one, but the most painful thing is to lose your own son or daughter. This is actually a good kidnap movie with some good thrills and heartbreaking moments. I also found it interesting how the police in this is so inferior in just about every way possible that it gets very freaking annoying, in fact I hated the police in this especially that fat women police person than the kidnapper himself. Although I am sure a lot of the stuff that happens in this movie is made up to keep the audience entertained, it's based on a kidnapping that took place in Korea. Where they never caught the kidnapper and the only trace they have is a recorded message left on the phone. There is a lot of what if moments in this movie, where you think what if things went differently a lot of times or if the characters made a slight different decision. Sol Kyung-gu also proves why he is one of the top actors in Korea, his performance made the final act even more heartbreaking and sad. The negative aspect is that this becomes a linear cat and mouse game, and the cat and mouse game aspect of it wasn't intriguing enough.

7.8/10

But not as another shill reviewer has stated "Better than Man On Fire" or "Ransom" - Utter hogwash.

Very average Korean Thriller based on a true story so do not think you are going to get a happy ending. Pretty pointless movie actually as it makes the Korean police look like the keystone cops; I was beginning to think it was a comedy thriller.

Very average (5/10) so only watch it if you have nothing else in your movie library!

The movie is pretty intense couldn't guess what going to happend next. All the time I thought, they would recuse the boy, and find the kidnapper. But at the end, It was really tough to watch when I knew that he was dead. The case remains unsolved and the killer (Kidnapper) won't ever punish because of limitation of time.
