I don't imagine too many people are precisely located in the center of the potential audience for a book like this than I am. I discovered comic books in 1966 when I was 7, and by the time covered in this work, basically 1972-1977, it seemed as if comics were growing up right alongside me. Not all of them, of course, but I was most impressed by the ones written by Steve Englehart, Don McGregor, and Steve Gerber, as well as some of the ones written by Doug Moench and Marv Wolfman. Borenstein does a deep dive into most of the comics I loved the most as a teen.
Borenstein is a comics fan, but he's a Professor of Russian and Slavic studies for a day job. The guy is extremely good at seeing patterns in these comic books that I only dimly understood at the time. I could tell they were different from all the rest, but Borenstein goes deeper into explaining what made them work (and what flaws they still had) than anybody I've read.
Doctor Strange, Captain America, the Avengers by Englehart. Werewolf by Night and especially Master of Kung Fu by Moench. Tomb of Dracula by Wolfman. Killraven and Black Panther by McGregor. Man-Thing, Omega the Unknown, and Howard the Duck by Gerber (though I wish he had made the chapter longer and covered the Defenders as well). Yes, comic books are a visual medium, and he does refer to the artists some of the time - but these writers were consistently different from the rest of Marvel's output at the time, and it's great to see them recognized.
