After "V for Vendetta", I chose to comment "Watchmen", which raises the bar a notch above. Much more than a database, it is a "graphic novel" - hear graphic novel - a nice pad vibrionnant colors, imagination and creative madness. The sum is a challenge because the flow rate is about 10 ideas to the page. We can say that it is a alternate history (whose cause is Dr. Manhattan, come from a nuclear accident) taking place in New York at the time of the Cold War, in a world of super ex -héros tired that will have to conduct their investigation to solve the murder of one of their own.
Exploding the "classical" laws of the genre, blending old-fashioned (sometimes gently retro style of some superheroes) and modern (cynicism, amorality, dark, pessismisme, world to the brink of the abyss) brilliantly, is Watchmen * * the postmodern graphic novel par excellence. Passionate and exciting work, studded with delicious portraits to be extraordinarily ordinary, extraordinary or ordinary, and packed with discoveries (even in the book into chapters) ... during these 400 and some pages that scroll to the speed of a tachyon, actually traveling in the head of Moore, and anything goes, even a small interlude on Mars.
In short, a work of Martian! But brilliantly awesome.
