Fiendishly efficient MC, like classroom of evil, yet pitted against strangely idealistic "villains"
Unlike the MC, who is not a dexter clone, the so-called "evil" people are strangely one dimensional. They embody a particular trait of society that most would overlook, in this case mysogeny, and cranks the dial to 11.
As bruce lee once said: "I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times"
I'd rather the MC face 1 interesting and memorable villain than 10,000 cannon fodder villains
For comparison "VIgilante" has the same premise but with a much more gripping, and often overly realistic sensation
P.S. the cannon fodder villains break far to easily, for the sake of a neat tie-in finish I guess, almost cathardic... After all no one wants to see a drawn out torture scene... *cue 007 getting whipped in the balls in casino royale
