Fan of old X-Men (80s to mid 90s is the best era) and Spider-Man books as well as Batman.

For more off kilter books, check out Johnny the Homicidal Maniac, Squee, and I am Sick, they were all done by the same guy who created Invader Zim.

Watchmen was great if a bit long winded at parts.

Sandman is pretty snazzy as well.
