Why Batman?

Psychiatrists...and psychologists...plus others interviewed in the History Channel documentary Batman Unmasked: The Psychology of the Dark Knight analyze Batman more than any other superhero — the character himself, that is. Looking at Superman psychologically means looking at modern mythology. He's the modern demigod myth. While there's something mythic about Batman too, to be sure, he's more akin to the mortal legends like Robin Hood and pulp heroes like Zorro and the Shadow, extraordinary men but men nonetheless.
