This list is very exciting, because of the comics I recognize and the ones I don't recognize. Herewith I provide a wonderful pulled quote:
Back in the mid '60s, The Fantastic Four was a monthly guarantee that you could pay ten cents for twenty-some-odd pages and witness the most batshit insane spectacles imaginable. Outside of religious text and Greek epics, Four was the only place where you could see a building-sized, purple-crowned man descending from the sky and threatening to eat the planet, and where the only people who could stop him were invisible or on fire.Of course I expected the Watchmen and Dark Knight here, which certainly changed my life, but the more recent options I haven't checked out yet get me revved up about a trip to a comics store.
Like all mediums, comics have a few exceptionally good examples and a lot of crap. The good stuff is as good as any other medium can deliver.
