Voltron: Legendary Defender
A great pick
Ages 8–13First shown 2016
For millennia, the evil Galra Empire has plagued the universe by conquering planets and destroying their inhabitants. The only known threat to the empire's power and plans is the legendary "Defender of the Universe," Voltron, a 100-meter-tall robot warrior composed of five lion mechas whose whereabouts are presumed to be unknown. The Galra Empire's path of conquest and search for Voltron has led them to Earth's solar system. A group of space pilots-Shiro, Keith, Lance, Pidge, and Hunk-discover the blue lion and immediately get swept up into the Galran War. They meet Princess Allura, become the next Paladins, and reunite the five lions to form Voltron and free the universe from the Galra Empire.
Our verdict
- Good influence 4/5
- Parent appeal 5/5
- Well made 4/5
Not toy-led No grating audio
Reviewers celebrate this series for its sophisticated storytelling, high-quality animation, and diverse cast of characters that appeal to both children and adults. While the early seasons are lauded for their tight writing and emotional depth, many observers noted a significant decline in quality and narrative cohesion during the final stretch. Despite these later issues, it is regarded as a visually stunning and mature space opera that successfully modernises its source material.
Why these scores
Good influence
Does it show behaviour you'd be happy to see copied?
4out of 5
The series is widely praised for its emphasis on teamwork, perseverance, and diverse representation, including characters who are people of colour, disabled, or LGBTQ+. While many reviewers appreciate the nuanced character growth and inclusive themes, some discussions note that the queer representation can feel minimal or tacked on at the end. A few viewers also raised concerns about occasional mean-spirited jokes or the depiction of persistent flirting as a romantic model.
Parent appeal
Will you enjoy watching it with them?
5out of 5
The show is frequently described as high-quality television that adults can enjoy independently due to its sophisticated themes, such as war, PTSD, and political intrigue. Most reviewers find the witty humour and complex villains engaging for all ages, though a few critics found the show lacked depth without nostalgia or felt the writing quality declined in later seasons. Overall, it is considered a rare example of a children's series that respects and captivates its adult audience.
Well made
Are the writing, animation and sound made with care?
4out of 5
The production values are exceptionally high, featuring a seamless blend of traditional and 3D animation, a cinematic synth-based score, and award-winning voice acting. However, there is significant consensus among reviewers that the writing, pacing, and overall coherence suffered a noticeable decline in the final seasons, with some describing the ending as rushed or unsatisfying. Despite these late-series flaws, the world-building and action choreography remain standout elements.
Watch-outs
Overstimulating: not enough data
We haven't found enough independent sources to say yet.
Not toy-led
While one reviewer suggested the generic fantasy elements might be intended for merchandising, other discussions highlight that the show focuses heavily on complex politics and espionage rather than robot-centric action, and that the limited toy line indicates merchandise was not the primary driver.
No grating audio
While there are isolated complaints about inconsistent audio levels or specific character voices being annoying, the vast majority of commentary highly praises the voice acting and soundtrack, which has received industry awards and nominations.
