Firstly let me say this is a film not for everyone.personally i loved it , acting was superb direction editing all spot on. as with all films of this genre from japan and and other Asian countries it will be remade (badly i may add ) by the more popular outlets of ,lets just say western money making studios. OK the plot is a bit of a slow burner at the start but soon picks up into an easy to follow story line (some might find the subject matter hard to stomach )but the acting is superb and the gory violence very believable at times. it is hard to compare another film like this where the acting and dialogue go so well together and the lead actor is a joy to watch (perfect casting).in my opinion better than battle royal and probably my fave film due to the acting and crisp and psychotic performance a gem.
