Soon's descent into a quagmire of revenge and her electrifying struggle with Soo will culminate into a riveting conclusion. Who will emerge alive — the hot-blooded Soon or the cold-hearted Soo?
"Monster is one of my all-time favorite thrillers. Lee Min Ki delivers an amazing portrayal of a man who's mind just isn't right. Throughout the performance, you aren't sure if you love him or hate him, if you want to hug him and wipe away his tears or cut his throat before he can do more damage.
Kim Go Eun's character was hard for me to understand at first. Her single-minded purpose shone through until the very end. Bok Sun becomes the every-man's-heroine, who manages to fight for her personal justice despite her disability. The gore value in this film is fantastic. My personal favorite is the chopsticks scene, which I highly recommend. I have watched this film several times, and it continues to thrill me, like my favorite roller coaster.
On top of all of that, the scenery is gorgeous, as it is set in a forested, rural area. The filmography was done beautifully.
I recommend this flick for lovers of the thrill. Lovers of blood. Lovers of psychotic evildoers and lovers of a good game of cat and mouse." "This movie was very enjoyable, a little fast paced but a really good watch. I enjoyed the the cast and how they portrayed each character. Kim Ko Eun portrayed the violent, dim witted bok soon very well and surprisingly I wasn't annoyed by this character. And one has to the the portrayal of the psychotic tea soo played by Lee Min Ki, I was glad that he really came over as this crazed killer. I can't say that I really loved the end where Bok Soon really proves how stupid she is but the very end with Bok Soon singing that song."
