Parents need to know that Marvel comics have ratings that range from "all ages" to "explicit content, 18+" for its MAX imprint of adults-only comics. Marvel doesn't offer MAX downloads or subscriptions online, so kids won't find any nudity, strong sexual content, or drug use on this site. Message boards are free of bad language and rude behavior, but the site's blogs may not be squeaky clean. Parents also need to know that the site is product heavy, sending users to toybiz.com to buy Marvel toys and to a Marvel e-commerce site to subscribe to comics.
