This is very good prison based movie. Acting of cast is top notch. A person who played negative role in 'midnight' thriller played as boxer/trainer in this movie. Inspirational movie and people who are interested in boxing must not miss this one.

Kungfu-fighting, muy tai, mma, ufc wrestling, karate , budo ,judo and boxing at a juvenile level then this is a treat. Verykorean in style and demeanors, hollywoodish in story and hong kongish on plot.

Its a juvenile delinquents story where fighting is done by the pecking order, and as it seems there are few guards and seemingly nonrealistic settings to be a correctional unit of the south korean government, but its a film after all...

there are much fighting, seems like some of the punch lines mustve thrown some of the actors to the medic for mending, and the power of violence is pretty high, the intro especially may make you gap.

So if you hunger for a good fighting film the grumpy old man recommends, but for the squemish rest its just another karate-kid set up. The production all over is a low budgie and not a black tulip like the best of south korean silver screen products.

Overall , it's an 'okay' movie, nothing special or memorable about it.

No character development at all, the story goes fast but still enough to keep you engage so I would say overall I enjoy the movie. Also flighting scenes and actions were sometimes a Little repititive but not bad.

I'd definitely watch the movie franchise tho.
