Indeed, I wonder if people who were fans of HCTB might have a problem with the book's portrayals, since it turns the show's villain into the hero (or at least antihero).
I was a fan of HCTB and I didn't have a problem with "Ishmael" at all, I thought it was a lot of fun. The thing is, there was a lot of females that liked Mark Leonard's character more than the others. He was the only reason my Mom watched the show in the first place. (She was also a Dr. McCoy, Scotty, Sarak fan in that order.)
