2015 72 min Science Fiction · Action · Animation ⭐ 7/10 PG-13 Dir. Ethan SpauldingWriter: Heath Corson US Production

Justice League: Throne of Atlantis is currently streaming in the US on HBO Max Amazon Channel and YouTube TV, and it earns its premise rather than just borrowing genre trappings. A tight runtime that never overstays its welcome. A 7/10 rating says what the writing already makes obvious: this one works. Sean Astin sets the tone, and the world-building does the rest. Start it on HBO Max Amazon Channel whenever you need something guaranteed to land.

Whatever else is competing for your attention this week, Justice League: Throne of Atlantis is worth clearing space for. Justice League: Throne of Atlantis uses its genre premise as cover for asking bigger questions. After the events of Justice League: War, Ocean Master and Black Manta have declared a war against the surface in retaliation of the aftermath of Apokoliptian-tyrant Darkseid's planetary invasion. Queen Atlanna seeks out her other son, Ocean Master’s half-brother Arthur Curry, a half-human with aquatic powers with no knowledge of his Atlantean heritage, to restore balance. Living with powers he doesn’t understand and seeing the danger around him, Curry takes steps to embrace his destiny, joining the Justice League, and with his new teammates he battles to save Earth from total destruction. Sean Astin and Rosario Dawson lead a cast that brings real weight to the material. It was released in 2015. Justice League: Throne of Atlantis resists the temptation to explain everything, trusting the audience to sit with ambiguity. There is real craft here, even in the moments that do not fully land.

Viewers burned by ambitious sci-fi that could not sustain its premise should give Justice League: Throne of Atlantis a chance. It has built its own audience without needing a direct comparison. The complete film is available and best experienced without too much prior knowledge of where it goes. Sean Astin anchors it with a performance that makes the more abstract moments feel personal. If you have been burned by ambitious sci-fi before, this is the exception.
