Centering around Superman's (John Krasinski) super-dog Krypto (Dwayne Johnson) learning to accept his owner's affection for Lois Lane (Olivia Wilde) and discover how to make his own friends in a group animals (Kevin Hart, Vanessa Bayer, Natasha Lyonne, and Diego Luna) who all become super-powered through a mad guinea pig's (Kate McKinnon) use of Orange Kryptonite, DC League of Super-Pets offers your basic animated kind of mildly diverting fun with the Justice League being completely unprepared to deal with super-villain animals and the need for our unlikely heroes to unite and form the League of Super-Pets.
While not likely a film I'd return to, and would prefer DC to drill into the untapped potential of Captain Carrot and His Amazing Zoo Crew! (think Justice League meets Tiny Toon Adventures), fans of DC (or anthropomorphic characters in general) should have a fine time.
