An assessment of “DC League of Super-Pets” by Tara McNamara on Common Sense Media deems it appropriate for ages six and up. McNamara notes that, being an action-y superhero movie, fantasy violence is plentiful, but often resolved such that those affected are shown to be ultimately unharmed. Its humor, meanwhile, can skew toward its adult audiences at times. In fact, it’s likely only adult viewers of “DC League of Super Pets” will understand a large portion of dialogue spoken by a turtle named Merton, voiced by Natasha Lyonne — not the sole source of its adult-oriented jokes, but one of the film’s principal contributors. While Merton hints at some sexual innuendo and uses swear words, the former is only ever implicit and the latter is bleeped.
Common Sense Media user realmom17 wrote in their own review, “Swearing is bleeped out fully but unexpected. Some animal violence caused our kids to get a bit anxious, but they held it together. Our 3 year old had to be held towards the end because of the final battle scenes.” They also suggested that its innuendo is only appropriate for children who are at least 7 or 8 years old. Some other users, however, felt that his humor crossed a line.
