I really think that maybe, just maybe, O'Neil's Batman is my favorite Batman. Today, anyway. I think I've run across a few of his stories I wasn't crazy about, but not a single one (so far) that Ive hated. And many, many I've loved. A while back somebody (batcookies, maybe) pointed out that he does have a weakness with titling stories rather... badly, but that I can live with.
Agreed. It IS interesting. Love how complex he makes the character.
