Heroes' mutual respect makes for a winning team.
Parents need to know that this show highlights teamwork and the heroes' respect for each other due to their unique strengths. While the male-to-female ratio within the League leaves much to be desired, the female characters who are in the group are on equal footing with the men. Kissing and occasional mild sexual implications (snuggling, etc.) might make the series a little strong for superhero fans under 7.
