In this movie, the cows are boys. They have big pink udders and manly male voices. In fact, head cow Ben has the manliest, malest, deepest voice imaginable, that of quintessential cowpoke Sam Elliott. Our hero, Otis has the voice of Kevin James. But there are some girl cows, too, Daisy (Courtney Cox), who is pregnant, and her friend and Bessy (Wanda Sykes). And, just to make things more confusing, there’s a bull off somplace, too.

It isn’t like they’re trying to make some sort of point about gender here or there’s some punchline about it. It’s just that the people who made this movie don’t care or think we won’t notice.

I blame computers for this. It used to take as long as seven years to make an animated feature film, with all those individual cells to be lovingly hand painted. So there was a sort of market reality helping to make sure that the scripts really merited that attention. All of a sudden there is software making just about any computer into a mini-Pixar and agents who tell their star clients they can be in the next Shrek. So we get a lot of mediocre films with meticulously detailed fur and feathers and leaves and sunsets and vague and generic stories and characters.

And we get junky animated movies like this one: uncomfortably interspersed with a lot of slapstick and cornpone humor is a cynically added plot line that’s a little bit The Lion King a little bit Henry IV.

Ben, a strong, wise leader has a son, Otis, who loves pleasure and partying. When Ben is killed, Otis feels responsible and unworthy but rises to the challenge of protecting his friends from the predatory coyotes.

If it was just jokes like a cow shouting “MAN-a-bunga!,” riding a mechanical man-shaped bronco, and a bling-wearing rapping rat, it might be silly fun for kids. But the scary coyotes, the sad death of a parent, and the weird wooing of a pregnant (girl) cow make it uncomfortably awkward. The cynical superficiality of the way the more serious material is presented makes it inappropriate for younger kids and unworthy of older ones.

Parents should know that this movie has some peril and violence. Coyotes attack the barnyard animals. A character is mauled. There is a sad death of a parent and a description of other sad losses. Characters use some crude language and there is some potty humor. The cows get drunk on milk and a man reaches for a six-pack of beer. There are diverse characters, but some stereotyping of the females. And there are some references to killing animals for food, which may disturb some viewers.

Families who see this movie should talk about the way parents feel when a baby is born and what it means to stand up for others. They should also talk about the way we sometimes blame ourselves when bad things happen and how we learn to take responsibility for our actions. They may enjoy talking about the ways the animals in this movie imitate human behavior.

This is lowest common denominator movie-making. Why not, it’s based on a lowest-common denominator comic strip.

Garfield’s lighter-than-air comic strip is utterly generic because its motivating force is not art or comedy but commerce; the less distinctive the character or situations, the better suited to appearing on everything from greeting cards and car air freshener to pizza and slot machines. Garfield is not a cat; he is a brand, as this excellent article in Slate explains.

Thus, we have this sequel, like the first movie, designed to work appeal to as broad an audience as possible in and outside the US. So the focus is on crude jokes that are universally understood and not much attention is paid to details like the fact that the title recalls Charles Dickens’ “Tale of Two Cities” but the plot is taken from Mark Twain’s “The Prince and the Pauper.” Or that some of the animals are animated and some are real; some can talk and some cannot.

Garfield (the computer animated cat with the voice of Bill Murray) and Odie (an actual dog with no human voice) stow away when their owner, Jon (Breckin Meyer) flies to London to propose to his girlfriend, Liz (Jennifer Love Hewitt), a vet. Garfield changes places with his look-alike, a fat orange tabby named Prince (the very plummy voice of Tim Curry) who is even more pampered than he is. When Dargis (Billy Connelly) tries to get rid of Prince so he can inherit a huge estate, he is in for double trouble.

It’s all obvious and synthetic, derivative to the point of plagiarism (there is a “mirror” scene lifted from both Duck Soup and “I Love Lucy”), but those who are happy just to see animals talk and bad guys get hit in the crotch will find some mild enjoyment.

Parents should know that the movie has some crude humor, including bathroom jokes and a dog biting a character in the crotch. There are some rude schoolyard terms and there is some comic peril and violence, including characters being threatened with a gun and a crossbow, but no one is hurt.

Families who see this movie should talk about why Prince and Garfield are so important to their owners. And they should make some lasagna!

Families who enjoy this movie will also enjoy the original and the many books of Garfield cartoons.
