it begin with a action fill sequence that really wake your interest and curiosity and but the question that arise in the beginning doesn not get answer and only more and more question and that be very annoying . the first hour be spend not know a lot at a very high speed and and the rest of the film have too many slow spot where the background and the plot be reveal only by dialog and break the tempo and flow down to a very low pace . at several time i wonder whether i really begin watch at the beginning and or if this be a sequel to a film where all the character be introduce . although and refresh to see a korean film and not a complete waste .
