Suspeito X

I've yet to see the original Japanese version of this story, but the Korean version is one more reason why I feel Korea makes some of the best movies around.

A story of logic and math, this story emphasizes the relationships over the usual mystery. It's about why did it more than how did it, and the ending like a character says is happy and bitter.

The acting in excellent and the music is also a great part in why it's so effective.

I'm not going to give a lot of detail about the plot or the characters. See the move on Youtube with English subtitles and enjoy.

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 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!!

This movie was remade by vijay antony 'KOLAIKARAN'. But this surprised than tamil movie.. A brilliant maths teacher try to help of his crush to escape from a murder.. Climax was soo stunning and explained well.. Must watchable movie..

South Korean cinema, definitely one of my favorites. They manage to surprise me every time. From all Asian countries, they're by far the best. No overacting like in the other Asian countries, instead you get more than decent acting. Yong-Eui-Ja X (or Perfect Number for the English title) is a slow paced crime thriller. Good cinematography, engaging story, and excellent acting. Maybe not the best South Korean movie but certainly worth watching.
