This Graphic Novel is everything you expect from Batman, perfected to an insane level. Frank Miller is a genius, every frame of his an art, showing us exactly what it would be like in Batman's universe. The final combat and the climax involving Superman and Batman is one of the best I have come across, in movies, books or TV series. 
 Strongly recommended. After all, "The world only makes sense when you force it to." Force yourself to grab a copy and the world will make more sense ;)
