As the DC Universe Animated Original Movies line continues to build a new shared continuity, beginning with Superman: Man of Tomorrow, this iteration of the DCU provides a glimpse at its possible future with its latest feature film, Legion of Super-Heroes. Boasting the Tomorrowverse's biggest cast yet, the movie not only gives the DCU's 31st century a well-deserved spotlight, but it also provides the clearest look at where this rebooted canon is going next. While the overarching conflict may not be the most engaging, its balanced cast, imaginative setting and accessible entry into the Legion mythos make the film worthwhile.

Barely surviving the destruction of Argo City, Kara Zor-El is sent to Earth where she follows in her cousin’s footsteps to become Supergirl. Noticing Kara having trouble adjusting to life on Earth, and her responsibilities as a superhero, the Justice League decides to send her to the 31st century so she can be mentored by the Legion of Super-Heroes. However, as Kara learns to fit in with the rest of the Legion, including its resident genius Brainiac 5, a menacing threat arises in both timelines.

At its core, Legion of Super-Heroes is the story of Supergirl (Meg Donnelly) and Brainiac 5 (Harry Shum, Jr.) learning how to trust each other, with the rest of the Legionnaires playing off their dynamic. Screenwriter Josie Campbell really leans into Kara’s journey, not just as a point-of-view character experiencing the 31st century, but as a complex protagonist with a solid character arc. Donnelly and Shum elevate the material, as does the extensive supporting cast, with even the more obscure Legionnaires getting an opportunity to shine.

Unfortunately, the action sequences hold Legion of Super-Heroes back. Opening with both the destruction of Argo City and a showdown between Supergirl and Solomon Grundy, these two sequences set a high bar for action that the rest of the movie struggles to live up to. The movie does make good use of its large roster and unique powers, but fails to live up to the opening sequence's super-powered first impression.

The animation style builds off what was previously established by Man of Tomorrow, with thick outlines around the face to make each character stand out. Director Jeff Wamester has been a constant presence for Tomorrowverse since 2021's Justice Society: World War II, and Legion of Super-Heroes is his most inviting movie yet.

A Legion of Super-Heroes movie is a daunting task given the sheer size of the team, its futuristic setting and the relative obscurity of its characters, but this film succeeds as an introductory piece. Though the movie could up the ante on some of its major set pieces, it does get to the heart of what makes the Legion tick.

Directed by Jeff Wamester, Legion of Super-Heroes is available Feb. 7 on 4K UHD, Blu-ray and digital HD.
