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.
