I have a problem with applying the term "Regrettable" to all of the superheroes discussed in the book as there are some that I have read and liked and others that would be interesting to read, so there is almost no regret on my part. Some of the heroes mentioned even had long runs or recurring appearances showing up in current issues. But, there was one superhero based on a real life daredevil named The Human Fly whose comic run ended when the real daredevil was seriously injured jumping over busses with a rocket powered motorcycle, which I think is the only one that everyone can agree was a truly regrettable comic character (poor guy). This book a fun read, especially if you're a generic comic book fan, and I loved most of the well placed tongue-in-cheek commentary.
