I will not entirely disagree with you. The pendulum swung too far. What Frank Miller started , making Bataman a very driven character, turned into a Batman for whom ,bruce wayne was just a farce and he sat at night alone in the batcave stabbing himself with a knife,just to see if he could feel anything.
I had really hoped that after Infinite Crisis th hardcore obsessive would be dialed back a few ...but it didn't really work out. There needs to be more interplay with Bruce wayne the person and Batman the avenger.
But Marv Wolfman is just so far off the mark with the first example.
