I prefer graphic novels more than comics (more meat!! more pages!! a bigger fix between issues) but I like both forms, and most forms of graphic art and animation.
I did read a lot of Marvel and DC comic when I was younger, but seem to have outgrown them.
Some of my favorites:
Prince Valiant (old, but very well drawn)
Batman (the ones by Frank Miller are brilliant, but very dark)
Lone Wolf and Cub - very popular series about a ronin assasin in feudal Japan. Great artwork, cracking story, gratituous violence and slashing (sorry if this offends anyone) *super fav*
Another fav for art is Eric Stanton - he drew a lot of erotic comics, especially domination and bondage stories (like this for the theme of his works,
) I've included an example of his work.
