The series sends positive messages about having a strong sense of self, having a strong work ethic, and the importance of family. A major theme is integrity,
Back-biting and scheming, but no violence (except to a stuffed bunny...).
Betty's boss, Daniel, is a womanizer who has no qualms about sleeping with his co-workers and getting sexual favors in the office -- but virtually all of his shenanigans are implied rather than shown (some scenes show him in a rumpled bed, another scene implies an indiscretion during work hours, etc.). Some female characters wear tight and/or revealing clothes. One character is transgendered.
Pretty mild: "Bitch," etc.
The world of Mode magazine is a very materialistic one, but most brands and designer names are fictional.
