If you like your dark comedies very dark, disapprove of justice tempered with mercy, think that the state spying on its citizens is a good thing and wish that happy ending were tinged with a bit more sorrow, then this is the play for you. If it is okay to act like a complete cad and utterly repugnant person but use the power over life and death reserved to the duke to cover your misdeeds you will love "Measure for Measure". If the sworn leader of a nation skulks off to hide, returning in disguise to see what chaos his absence has caused seems like a good idea then dig right in to one of the most problematic of Shakespeare's problem plays. 
 Or if you disapprove of such thoughts, actions and desires your feelings will be confirmed by "Measure for Measure". Good versus evil, justice versus mercy, courage versus cowardice--it is all there for the taking. I have now read the entire play all the way through for the fourth time and am looking forward to the fifth.
