Just recommended Frank Miller's RONIN to someone, and got me thinking-- what are the *Must Read* GNs?

For me...

WATCHMEN
DARK KNIGHT RETURNS
DAREDEVIL BORN AGAIN
MAUS
CAMELOT 3000
BATMAN YEAR ONE
INFINITY GAUNTLET
X-MEN GOD LOVES, MAN KILLS
BLANKETS
LAIKA

What are yours?

There are MANY runs of books that I reread in collected form - SANDMAN, Y: THE LAST MAN, Simonson's THOR, Claremont/Byrne X-MEN, lots of classic Spider-Man runs...

...So I guess I'm talking more like GN's where you hold all of it in your hand in one go.
