I highly recommend french comics - or "bande dessinée / BD" as they are called there. I believe France has the biggest and most interesting culture when it comes to comics - so many different kinds of genres, art styles and forms are alive there. Reading "L'Incal" as a very young and slightly unattended child in a french bookstore put some really freakish images in my mind.

Sure thing! Can you recommend a few with good english translations - if that works?

Great, give "Doomsday Clock" limited series a chance after you finish with Watchmen, it's an interesting crossover with mainstream DC Universe.
