No, comic books don't interest me. I would rather see more original films, not ones based on comic books or other material.
If I were to put money on guessing one you probably liked - Persepolis.
A History of Violence also turned out okay. Having not read the source material, I'm guessing that's more because Cronenberg directed it than anything.
I remember there was an interesting graphic novel adaptation of Paul Aster's City of Glass way back when. I'm not sure what an adaptation of that adaptation would have to do to capture the spirit of what both source materials contributed though...
