This. I like Batman, but I sure as Hell can't/won't don't want to pick up everything and haven't read too much, save Year One, Long Halloween and a few others. For a looser fan, Morrison seems to be doing a genuinely interesting job of summing up all the points about the character and adding his own interesting little wrinkles to the idea, like this, which I'm thinking will probably turn out to be the ultimate sumnation of why Bruce Wayne needs to be Batman, somehow.
But I've really liked Morrison's run. Stuff like the Three Ghosts of Batman, the Club of Heroes and the like and RIP itself were thrilling.
