When I first heard there was a new “Teenage Mutant Ninja Turtles” movie in the pipeline, I wondered, “Why?” From their beginnings as a superhero parody comic by Kevin Eastman and Peter Laird to becoming a surprise cultural phenomenon, the anthropomorphic turtle brothers have been rebooted as a television show, toys and a bunch of movies.

The difference this time around is that “Teenage Mutant Ninja Turtles: Mutant Mayhem,” a new animated adventure now playing in theatres, captures the irreverent, rambunctious spirit of the comics that inspired it, without losing any of the heart that made turtle brothers— Leonardo, Michelangelo, Donatello and Raphael—so beloved in the first place.

An origin story, the new movie is a coming of age for the resourceful Donatello (Micah Abbey), the charming Michelangelo (Shamon Brown Jr), the reliable Leonardo (Nicolas Cantu) and the brave Raphael (Brady Noon). Raised by a mutant rat named Splinter (Jackie Chan) in the sewers of New York, under the orders of their overprotective, adoptive father, they only visit the human world to gather supplies. Splinter does not trust humans, and fears for his son’s safety if they are exposed to the human world.

But the turtles are restless. They long to be accepted, to go to high school, to do the things they see human teenagers do on television and in movies. “If we weren’t monsters, shunned by society, what would we do?”

On one of their clandestine visits to the city, they meet April O’Neil (Ayo Edebiri), an aspiring journalist who wants to tell their story. “This is insane,” she says. “Turtles. Mutant. Karate. Teens. I want to know everything about you.”

Meanwhile, New York City is being terrorized by Superfly (Ice Cube), a mutant housefly with a plan to kill and capture all humans and turn all animals on Earth into mutants. “Humans will be executed, enslaved, turned into food. Could be pets,” he says. “Any crazy thing you can think of, pitch it.”

Teaming with April, the turtles plan to take on Superfly and become heroes. “We take out Superfly and then everyone will think we’re cool,” says Donatello. “They’ll accept us!”

“Teenage Mutant Ninja Turtles: Mutant Mayhem” has a loads of scrappy heroes-in-half-shell spirit. The gorgeous rough ‘n tumble animation is computer generated, but feels organic, like a mix of the hand-drawn aesthetic of Ed “Big Daddy” Roth and Gerald Scarfe. It’s vibrant, exciting and will give your eyes a workout.

The story isn’t quite as exciting. It won’t take you anywhere really new, superhero movie wise, but it does update the TMNT lore. The use of actual teenagers to voice the four turtle brothers brings youthful energy that also adds some oomph and even poignancy to their coming-of-age/outsiders storyline.

The real stars of the show are Edebiri, Chan and Ice Cube. No longer just a supporting character, Edebiri gives April three-dimensions, with foibles–sometimes her nerves get the best of her—and objectives that help guide the story. Chan is very funny, but also humanizes the rat with his overly protective fatherly concerns. Ice Cube brings a considerable amount of swagger to the megalomaniac Superfly, spitting out his lines with humor and some cartoony menace.

Seven feature films in “Teenage Mutant Ninja Turtles: Mutant Mayhem” does something kind of remarkable. It takes a decades-old franchise and makes it feels contemporary with humor and heart while still providing a nostalgic blast for long-time fans.
