The movie is cute overall, but it has several bleeped out cursewords.
It also made a racist joke when Kevin Hart's character tells Krypto: "Every dog can use its nose to smell, even a white dog like you".
It's just not necessary to have a racist joke like that in a kid's movie. We try hard to not be racist and tell kids to be kind to each other, but how can we do that when a movie that is rated PG is making jokes like that?
