Ternet Ninja 3 Review: A Treat for Danish Animation Fans

This Ternet Ninja 3 review starts with a simple question: what happens when a hero outgrows his own adventures? Anders Matthesen's Danish animated series returns with a third film that puts growing up at the centre of the fun. It is a sharp, lively action-comedy with more on its mind than its premise suggests.

Ternet Ninja 3 Review: The Story So Far (No Spoilers)

The Ternet Ninja 3 plot picks up with Alex, whose appetite for ninja missions is fading. He would rather hang out with his friends than chase another adventure. His pint-sized Checkered Ninja, voiced by Matthesen, takes this badly and feels overlooked, and he is itching for a new mission.

Then things go wrong by accident. Alex ends up in a conflict with Marco, the bad-boy boyfriend of Jessica, and the trouble is one he never asked for. Checkered Ninja pushes him to stand up for himself. The film's tagline sums it up well: you can ignore your problems, but you can't escape them.

That is as far as this review will go. The setup is simple and relatable, and it leaves plenty of room for surprises.

What Works in Ternet Ninja 3

The best idea here is the emotional hook. Alex and his ninja friend are no longer in sync, and that gives the film a real relationship to build on, not just a string of fights. Anyone who has drifted away from a childhood obsession will recognise the feeling.

The film also keeps a brisk pace. At 84 minutes, it moves quickly and rarely lingers on a joke or a set piece for too long. As an animated action film, it balances slapstick, school-age drama and ninja mayhem without losing its footing.

Matthesen's writing is the engine. He created the character and writes the script, so the humour has a clear, confident voice. Fans of the earlier films will find the tone they love, and newcomers can still follow the story.

A Familiar Danish Sense of Humour

The comedy is cheeky and a little rude, in the way that has made the franchise a favourite in Denmark. It is the kind of animation that speaks to teens and older viewers as much as to children. If you enjoy animation movie reviews with some bite, this will suit you.

Ternet Ninja 3 Cast and Performances

The Ternet Ninja 3 cast is a small voice ensemble led by Anders Matthesen as Ternet Ninja. His performance is the heart of the film, mixing bluster, hurt feelings and sudden warmth. It is the kind of voice work that makes a cartoon character feel like a real friend.

Around him, the supporting voices keep things grounded:

• Flora Ofelia Hofmann Lindahl as Emily

• Louis Næss-Schmidt as Aske

• Emma Sehested Høeg as Jessica

The younger voices sound natural and unforced, which helps the school scenes feel believable. Their banter gives the film a lived-in quality that many animated sequels miss.

Where Ternet Ninja 3 Stumbles

The film is not without flaws. Its humour is rooted in Danish culture and in the earlier films, so some jokes may land less well with viewers who are new to the series. Subtitles can also blunt the timing of fast comic dialogue.

The bully storyline is familiar too. Teen conflicts with a rival and a love interest's boyfriend are well-worn territory, and the film leans on a few expected beats. It handles them with energy, but it rarely reinvents them.

Finally, the audience reception so far rests on a small sample, so it is wise to treat early praise with some caution. Even so, the tone of the response is warm.

Is Ternet Ninja 3 Worth Watching?

Yes, if you like irreverent animated action with a human centre. Directed by Thorbjørn Christoffersen and Matthesen, it delivers a quick, funny and surprisingly sincere story about growing up. At 84 minutes, it respects your time.

The film works best as a franchise entry, so fans of the first two will get the most out of it. Still, the clear premise makes it approachable for newcomers who enjoy action movie reviews-style adventure mixed with comedy. If you are asking whether Ternet Ninja 3 is worth watching, the answer is a confident yes for the right audience.

The Ternet Ninja 3 release date is listed as 1 January 2026 for Denmark.
