I guess the key is to define what the character roots are to see if that is what attributes batmans popularity over superman. Batman I dont think is as close to its roots at it has been mentioned and i think our current society is more sophisticated that its easier to accept a character of batmans nature than a character of supermans age old nature.
For every superman revision, there has been an equal batman revision. byrnes revision could be an equivalent to frank millers year one, electric superman can be compared to knightfall batman, death and revival can be compared to the breaking of the bat and prodigal, etc etc.
I personally think batman has grown as a character more than superman. Writers and fans have been sensitive to any type of change to superman and now we are faced with a character that the current culture doesnt seem to want to identify with maybe because its dull? not sure. any help sorting this out would be apreciated
Here's what I feel are Batman's roots and core attributes:
The tragic origin
Bruce Wayne nothing but a disguise
Grim character with gothic overtones
Master Detective
Operates mostly at night
Has a harsh and uncompromising out look
Rogues gallery of bizarre and twisted villains
Also portrayed as a father figure
Uses hi-tech equipment
Uses wealth to further his crime fighting
Master escape artist
All of those were developed between 39-43, and all of them still exist today, some emphasized more than others. Batman may have grown, but he hasn't gone completely off his original core...in fact he retains all of it.
Here are what I feel Superman's roots and core attributes are:
Origin with a Utopian world failing to save it's people due to it's own arrogance
True alter-ego with Superman as the reality, Clark as the disguise, the transformation to Supes representing wish fulfillment.
Orphaned twice, no parental or mentor figures
Strong social conscience and dedication to helping the oppressed
A certain amount of cockiness, close to arrogance
A somewhat lonely existence; Supes was the only major superhero without some sort of sidekick or romantic interest who shared his secrets; this would have changed early on if DC hadn't killed the K-Metal story, however. But 1938-1986 Superman was ALL about pathos. Even his friends were kept at a distance from him.
The entire newspaper angle and how it played into Superman's quest
Of those elements, they kept...the newspaper. The Modern version is a character with no pathos, no real suffering. His parents get to see him grow up, he has friends to share his secrets with, he doesn't have the burdens of Ma and Pa Kent dying or memories of Krypton's destruction or Lex's fall from grace or Kandor's perpetual shrunken state that he cannot solve...modern Superman has it so easy. He has Lois. If he fails, it's not the end of the world. There's just...nothing...there to grab onto.
Modern society could embrace Pre-Crisis Supes if his power level was lower much easier than modern Supes, imo. A character with depth and a good degree of quiet personal pain that he deals with because he puts the needs of others first is way more interesting to me that a super clean Big Blue Boy Scout with no suffering or pain. Superman should be about helping people and the incredible responsibility he feels. Now he is supposed to represent "hope" or some such Kumbaya crap.
