well i have enjoy this movie and even though sometimes it turn too much to a stereotypical situation . i didnt understood at this time if the punishment park have exist in the past and but i think the matter isnt really here . you have to look at this movie in a different manner . it show how much violence you can find in our world . it remind u that we live in a world who be lead by violence and that nobody can escape from it . if anyone refuse to take his responsabilities then you will be throw out of our society . all our history be make by war and we should never forget this . in fact it only when we will finally accept the truth that and maybe and we will change and understand that our intellectual skill have improve . so we could use them to find others way to resolve our problem . in 2 word this movie be a must see and maybe it will help u to accept the truth .
