I first saw this in 2012. Revisited it recently.

This is the second adaptation of the novel The Devotion of Suspect X.

This is the Korean version with amazing performances. Sorry, i ain't aware of the names.

Being a Korean movie, it has some melodrama but I liked the ending of this version much better than the Japanese version.

The hardwork of the math teacher goes futile in Jap version but here in this version it doesn't.

While the Jap version has the mother n daughter, this one changed it to aunt n niece.

While in the Jap version they showed the physicist's amazing problem solving skills where he solves a crime via the explanation of physics.

This version doesn't showcases his skills.

I'm yet again going to tick the spoiler button because toward the end of the review I am going to give away the ending. SPOILER ALERT

Now, I love Korean movies and that as well as the great reviews this movie has been getting may have been setting me up to watch this with way too high expectations.

For me this movie bombed. a 7 out of 10 in any other movie genre is not a bomb but for me, for South Korean movies 7 out of 10 is a loss.

I found the plot maybe a little to contrived, set out way too precisely and by the time they got to the huge twist I really did not care.

SPOILER BELOW!! The thing that got me the most was that the main character went to so much effort to obscure the murder of the x-husband that he hid the x- husband's body where no one would ever find it. Killed a homeless person the very same way and hid their identity so that the police would think that it was the x-husband's body.

A] The first part of this plan would have done the trick.Hiding the body where it will never be found without killing another person seems like an okay plan. B] No one care about the dead homeless person. "Oh you really love me, you killed a homeless person for me" I think the movie really fails to make a distinction that homeless people are actual people and killing a homeless person is still murder.

I never watch the Japanese one, some of the viewer who watch the Japanese one will think something else after watch this. Just like when you watch fincher's dragon tattoo after the Swedish one, which one is better? So, I'm hardly rate ten star because no such perfect movie in this world, this movie either. But, something all moviegoers need is the movie that have some kind of spirit, which it can hold you to stay on your seat till the end of credit. Make your mind think like this is not right? What's going on? What will happen next? Should sequeling this! A love movie that doesn't need ''I love you'' quote.

What I don't like about this movie is,they should make it more longer,because we love to see what will happen to the character's life. I'm so sad, a good romance-detective-mystery movie. Highly recommended!!
