Thereâs no coming back from collaborating with Vanilla Ice, as the Teenage Mutant Ninja Turtlesâ disappointing film and TV efforts over the past three decades bear out. Teenage Mutant Ninja Turtles: Mutant Mayhem (in theaters August 2) is yet another attempt at revitalizing their relevance, and its expressive animation almost does the trick, lending distinctive style to the crime-fighting foursomeâs latest big-screen outing. Such aesthetic panache, however, canât totally rehabilitate a franchise that was never cool to begin with and hasnât aged well since, nor can a script co-written by Seth Rogen and Evan Goldberg that vainly strives to update the heroes in a half shell for the 21st-century crowd.
Mutant Mayhemâs sole notable calling card is its unique aesthetic, with Mikros Animationâs visuals boasting a hyper-real quality that highlights the (artificial) brushstrokes of its character and environmental models. Director Jeff Roweâs film is a wholly CGI affair that looks like itâs been hand-crafted, its surfaces (sewer walls, city skyscrapers, explosive clouds of smoke) embellished with bold and scribbled lines. That approach bears a passing resemblance to the imagery of Spider-Man: Across the Spider-Verse. Alas, the comparison isnât exactly flattering; whereas Joaquim Dos Santos, Kemp Powers, and Justin K. Thompsonâs superhero blockbuster was a gonzo amalgam of disparate styles, this reboot picks a single lane and stays in it, save for a brief fantasy sequence that has the appearance of a childâs drawings.
Whereas Mutant Mayhem tries something formally new, itâs otherwise far less adventurous than Roweâs prior The Mitchells vs. the Machines. A brief prologue relays how, 15 years ago, Dr. Baxter Stockman (Giancarlo Esposito) sought to alleviate his loneliness by creating a new family with a green mutant serumâsubsequently referred to as âooze"âcapable of turning bugs and animals into humanoids. Unfortunately, his evil rival Cynthia (Maya Rudolph) coveted the potion and, in a special-ops raid of Stockmanâs lab, the scientistâs beloved fly escaped death and a vial of the ooze rolled through a grate and into the sewers, where it coated four baby turtles as well as the adult rat, Splinter (Jackie Chan), who found them.
In the present, Splinter is the cautious surrogate father to Leonardo (Nicolas Cantu), Donatello (Micah Abbey), Michelangelo (Shamon Brown Jr.) and Raphael (Brady Noon), teen turtles named after Italian Renaissance greatsâalthough Mutant Mayhem doesnât allude to such art-history roots (the protagonistsâ monikers are shortened to Leo, Donnie, Mikey and Raph). Rather, its focus is on making modern-day references that its adolescent audience will know, from Beyonce, Batman, and Avengers to Attack on Titan, Tokyo Drift, and Wendy Williams.
The Teenage Mutant Ninja Turtles were always juvenile and Roweâs film panders to its target demographic, replete with one Turtle twerking and their newfound human acquaintance April OâNeill (The Bearâs Ayo Edebiri)âa fledgling high-school reporterâuncontrollably vomiting on-camera due to extreme nerves. Given the proceedingsâ general immaturity, the fact that thereâs no potty humor should be taken as a minor victory.
Adults wonât find much to latch onto here unless theyâre the sort who delight at characters using contemporary slang like âsusâ and ârizz;â the only way in which Mutant Mayhem caters to over-12 moviegoers is with its soundtrack, which uses â90s cuts (Blackstreetâs âNo Diggity,â Olâ Dirty Bastardâs âI Like It Raw,â A Tribe Called Questâs âCan I Kick It?â) to keep them from falling asleep. Still, a kiddish tone isnât the death knell for the film, and its graphic-novel flair is intermittently enlivening.

Roweâs action is dynamic, and he does just enough to carve out his protagonistsâ personality: Leonardo the dorky goody-two-shoes leader; Michelangelo the loud and aggressive bruiser; Donatello the geeky staff-wielding brother; and Raphael the headstrong complement to his siblings. None are particularly captivating, but theyâre faithful to their origins.
Rogen and Goldbergâs screenplay (co-written with Rowe, Dan Hernandez, and Benji Samit) is verbally hyperactive and narratively straightforward. Desperate to be a part of the human world that Splinter distrusts, the Turtles befriend April, indulge their heroic impulses, and cross paths with a criminal bigwig whose gang has been making headlines stealing high-tech equipment.

The villain in question turns out to be Superfly (Ice Cube), Stockmanâs former guinea pig pet, who shares the Turtlesâ desire for acceptance. Itâs his methods that turn out to be the problem, because Superfly intends to build a machine that will transform every living creature on the planet into a mutant. Much chaotic combat ensues, including a car chase through New York Cityâs bustling streets and a final showdown in crowded midtown between the foursome and a horrifically enhanced Superfly.
Considering Rogenâs participation as both a writer and actor (he voices mutant warthog Bebop; John Cena is his burly sidekick Rocksteady), itâs surprising that Mutant Mayhem plays it so safe, not merely in terms of plot but with regards to its comedy. T
here isnât a single inspired line to be found in the film; instead, it expends most of its energy on routine nods to the Turtlesâ love of pizza, a single utterance of their catchphrase âCowabunga,â and repeated jokes about the quartetâs fear of being milked by humans. Meanwhile, the storytelling is sloppy, so that Cynthia is barely defined and unceremoniously discarded, and Superflyâs motley cohortsâwhether itâs skateboarding gecko Mondo (Paul Rudd), singing manta ray Ray (Post Malone) or bat Wingnut (Natasia Demetriou)âare sketchy afterthoughts.

Despite a surplus of commotion, Mutant Mayhem feels remarkably small, thanks to an adventure that takes place in a confined geographic space and a conflict that begins and ends in swift, simplistic fashion. Its funniest gag arrives during an early flashback to the Turtlesâ martial-arts education, which comes via viewings of Kerry Li's Guide to Self Defense, YouTube clips, and old Hong Kong moviesâone of which features none other than Jackie Chan himself.
Cleverness, however, is in short supply throughout the rest of this functional endeavor, as Rowe and his collaborators tick off items on their IP checklist and diligently avoid deviating from formula. Such cautiousness prevents it from sinking to the depths of previous TMNT franchise entries. Yet in a post-Across the Spider-Verse animation landscape, standing out requires significantly more coloring outside the lines.
