How might the 1938 print debut of the Superman mythology be revived? by focusing on his canine friend.

At least such is the idea of Jared Stern's reasonably inventive animated comedy "DC League of Super-Pets," which he also co-wrote (Warner Bros.).

The dog, who has gone by the name Krypto (voiced by Dwayne Johnson) since he was a puppy, has reportedly been loyal to the Man of Steel (voiced by John Krasinski) without fail, 

according to Stern's screenplay, which he co-wrote with John Whittington. 

But Lois Lane's attraction to Superman upsets their close relationship (voice of Olivia Wilde).

What's more, Lulu, a cunning guinea pig who has acquired powers (voiced by Kate McKinnon), is risking their safety. 

Krypto turns to a team of equally skilled rescue animals led by Ace (voice of Kevin Hart), 

a rough dog with a kind heart beneath his tough exterior, in order to defeat her.

As the group battles evil, they learn valuable lessons about the value of authenticity, the value of cooperation, and the selfless nature of true love. 

Although unnecessarily convoluted (three different types of kryptonite are mentioned in the script, and 

several of Superman's other DC characters make quick appearances), its plot is occasionally amusing and generally likeable.

although not quite. Due to the predictable potty jokes, a mention of Superman and Lois' pattern of spending some of their nights together, and 

a number of bleeped-out but clearly audible swear words, the movie cannot be suggested for extremely young children.

On the other hand, teenagers are more likely to accept these characteristics. 

The question is whether they'll be as susceptible as their juniors are to Stern's somewhat overused soft charm.

One subliminal reference to premarital sex, a few scatological jokes, some edited coarse language, and one obscene epithet are all present in the film. 

The Catholic News Service assigns an A-II classification to adults and teenagers. The PG grade from the Motion Picture Association suggests parental guidance.
