Jack Knight is arguably the most realistic and complex superhero ever created. He doesn't wear tights, instead opting for a leather jacket, tank goggles, and a sherriff's star that he got from a cereal box. He doesn't always win his fights, and takes more than his fair share of brutal beatings. He often has to think and talk his way out of situations, although when he does have to throw down, he is more than handy with his cosmic rod (yeah, I know, it's immature, but it's funny).
Anyway, the series wasn't without its flaws. When I kept up with it from month to month, I would often get impatient, as it took a long time to get to the explodo. Reading it in collected form isn't nearly as frustrating. Also, when I had another non-comics friend from college read the book, he said that there were too many references to other comics, and that he felt lost.
I don't really agree with that, but I accept that I may not be fully divorcing myself from my fanboy nature, so I'll include his criticisms as a caveat.
Recommended for: people who wish superheroes were more realistic; collectors and hobbyists.
Not Recommended for: impatient people, people who like lots of explodo (it delivers, but sporadically).
