Pros
It was fun to work with people who loved the product they were producing. Most, if not all, of the editorial staff were the kids who hung out in comic shops every day. the hallways of the editorial staff is the adult version of the clubhouse they spent their youth poring over every page and swooning over every superhero pose.
Cons
The clubhouse mentality is strong there, and any new idea is quickly smashed. Editors basically act as asssistants to the writers and artists, not contributing anything of value except to keep track of schedules. New talent is avoided, fresh ideas unwelcome. The staff is comprised of bloated middle-aged men completely out of touch with the younger generation of comic readers. They treat their characters like precious toys, not shared with new audiences. While meaningful work is minimal, people are pressured into working long hours, recognized for how long they sit at their desk instead of the work they accomplish. The top writers and artists are given all the power while new talent that may have something more to offer, treated passive-aggressively. Workers are expected to be profoundly grateful for the opportunity to work there and constantly reminded that there is al ine out of the door with possible replacements. There is no loyality to hard work, no respect shown to people who treat this as a career or a business. Instead, childish behavior is rewarded and promoted. Divisions that actually make money for DC Comics, such as marketing, licensing, are treated like second-class citizens. Sitting in meetings with real business people was great theater. I still don't know how they were able to keep a straight face sitting across the table from these jokers.
