i'm a huge comic nerd, but i tend to lean toward the non-superhero genre.
sorting by author:
jeffrey brown- clumsy, unlikely, AEIOU, i am going to be small, minisulk, little things, every girl is the end of the world for me, funny misshapen body
daniel clowes- david boring, ghost world, 20th century eightball, ice haven
craig thompson- blankets, carnet de voyage
liz prince- delayed replays, will you still love me if i wet the bed?
chris ware- jimmy corrigan
adrian tomine- optic nerve series
andy runton- owly (the way home & the bittersweet summer)
charles burns- black hole
marjane satrapi- persepolis
scott mccloud- zot
i've also read the watchmen
right now i am pining for the collection of little nemo: adventures in slumberland that were drawn in the early 1900s... supposed to be very surreal and even darker than the movie i loved so dearly as a kid :3
