For me in the late 90's/early 2000's it was Impulse and young Justice. The fun, animated style adventures kept me happy when I was stuck in a lot of crappy, isolating jobs back then. It was no Watchmen or Dark Knight but it was my little comic. I'm happy that Bart and YJ will be back courtesy of Bendis but it'll never the same (or will it?).
What was your little treasure?
