WSJ nails it

But by far the most charming and enjoyable parts of the book are those that present substantive artists like Mr. Ware, Jaime Hernandez ("Love and Rockets") and Jeffrey Brown ("Unlikely"). By a quirk of the comics industry, artists like these, who deal with the stuff of real life and whose work is treasured by people who read books that have spines, are tagged as "alternative" or "underground." It's amusing to see how, in "Leaping Tall Buildings," such artists come off as normal, thoughtful people, while contemporary superhero creators tend to come off as pretentious autodidacts or failed cult leaders. If anything is "underground," it's their insular, indecipherable comics.

Wall Street Journal tells it like it is.
Also great is the part where the University Of Chicago is described as "where fun goes to die."
