And, actually, I think Morrison's DC work SHOULD have charts and study guides...
To take your point about Law & Order focusing on a thin sliver of Lenny Briscoe's life, leaving out all he does when he's not on The Job, part of what I find out of whack about the Batman titles is that they're only about Batman on The Job. Worse, the Batman we have been shown for a long, long time is quite unlikeable.
I was going to say something similar to this, but Clark beat me to it. Plus, there were at least tidbits dropped into Law & Order of what he was doing when we weren't watching him.
For me concerning Morrison's Batman work. I was either indifferent or didn't like it until Batman & Robin. I like it, I just don't wet my pants over it.
