I cannot justify giving this film any higher of a rating...

Sure, the main actresses, both sisters, played theIr parts well, the support cast did an excellent job playing the vilians, and the other bit parts all added to the overall "feeL" of this film...both supporting the main actresses and making the plot believable.

The colors were vivid, especially the over-use of the color 'red', not just the blood, either.

But WHY would anyone in the their right mind would want to sit through a movie that 'insinuates' a 'special needs' teenage girl being raped several times, even though it was most suggestive rather than blatantly excessive; no nudity, thank God! Also, why would anyone want to see a lovely lady, dressed in red (probably to hide her bleeding if she got hurt; I am joking here), but the color 'red' is a major symbol in this movie, but I am not going to go there in this review).

You can watch Clint Eastwood in his DIRTY HARRY series, you can watch Bruce Willis in his John McClan character in the DIE HARD franchise, or a dozen other similar films. Does the 'hero' being a 'heroine' beating everyone up make this film any more worth watching?

The older sister Park In Ae (Lee Si Young) was justified trying to rescue her younger sister (Park Eun Hye, played by Park Se Wan) but other avenue could have been taken: get the media involved and the girl would become so hot that they would gladly give up gettng their money back and protecting their 'business' overall.

I agree with a lot of what was said by other reviewers before me, but my main reason for writing this review is

1) When was the line between justice and overstepping boundaries crossed in this movie?

2) The worst part of this movie is that it shows how GREED and LUST drives the sexual slave market; everyone, including an old man, who wanted to get a piece of the teenage girl and even try to make a buck off of further sexual 'use' of her; it's all I could do to fast forward through the blood and guts and the passing on of the girl to someone else!

I guess my work in emergency services: ambulance attendant, Emergency Room technician, Warm and Hot lines, and Rape Advocacy over the years, took control of me in the opening sequences; I enjoy a good shoot-em-up and 'Dirty Harry'-type movie occasionally, but not involving teenage (especially) special-needs girls being molested time and time again.

I feel that the director 'sold' out to make this movie more appealing to an American audience, my main problem with the way a lot of newer Asian movies are slanted!

RE-WATCH: Never again!
