I liked. The book is good, more of a period crime book than a Superman story. DeHaven is clearly inspired by the original Action Comics run, so Clark is more a social crusader than nowadays, but he also goes with the regular farm boy approach with Superman having a average intelligence.
My only real problem with the book, is that a lot of times it feels like the author was more interested in his original characters than in Clark, with a lot of space dedicated to them, perhaps in detriment to Clark's development. I have this theory, that Tom DeHaven used some plot and characters of some crime novel he had shelved as the bones It's Superman.
