Fourteen years after the first “Ice Age” animated film was a hit, the fifth installment in the franchise, “Ice Age: Collision Course,” rolls into theaters. Is it inevitable? Yes, 2012’s “Ice Age: Continental Drift,” was the highest-grossing animated film that year. Is it necessary? Absolutely not. “Collision Course” is simply a perfunctory, watered-down entry in the series that feels like it should have been released on home video.

In this world of ancient animals — wooly mammoths, saber-toothed tigers, flying dino-birds — facing apocalyptic, era-shifting, asteroid-borne problems, it feels profoundly odd that the emotional stakes of the film are centered on the wedding of Manny (Ray Romano) and Ellie’s (Queen Latifah) daughter Peaches (Keke Palmer). Not to get too nitpicky about a fantastical film for children in which a group of animals blows up a bunch of crystals in a volcano to set an asteroid off course, but the concept of marriage is decidedly anachronistic here. Also, they’re animals. When anything’s possible, centering a story on something as mundanely heteronormative as a wedding feels wildly unimaginative.

Romano’s Manny remains the heart of the group, but the chemistry and the writing between the characters is profoundly lacking. It’s almost as if they seem to be on separate, equally underdeveloped storylines. The most time is given to Manny’s issues with his immature future son-in-law, Julian (Adam DeVine), who plans to move away with Peaches after their wedding, in a sort of “Father of the Bride”-style storyline. The other characters are granted tossed-off story scraps as they are led on a hunt for magnetic crystals by the swashbuckling Buck (Simon Pegg).

There’s an oddly grotesque style to some of the character design, including the pop-eyed sloths, as well as the hijinks of the single-minded and physically elastic squirrel, Scrat. In chasing an acorn, Scrat ends up on a spaceship that sets off the whole asteroid debacle. There’s a certain amount of visual comedy fun to be had with simpleton Scrat, but his adventures in space take an extreme physical toll on the rodent.

The laser focus on something as innocuous as a mammoth wedding weighs the story stakes in the wrong direction — away from the actual world-ending part of the tale, which you would assume would take precedence. All of the apocalyptic stuff feels so very slapdash and silly, particularly a sojourn to “Geodetopia,” an opportunity to pillory yoga-practicing, crystal-loving hippies (much in the same way “Zootopia” already did this year).

Nothing comes together in “Ice Age: Collision Course,” which feels like the franchise grinding to a disappointing halt. Despite all the star power involved, the voice acting performances don’t inspire, the visuals are basic, and in 3-D, dark and dim. This would work much better as weekend background home entertainment, where the patchwork story and humdrum design can be easily looked over. This is one installment that didn’t need to be made, and in a summer of fine animated fare, “Ice Age: Collision Course” is only for the die-hard fans and franchise completists.
