Twelve has been quietly earning a loyal audience, and right now it is all available in Australia on Disney Plus, and in the US on Hulu. Don Lee leads a cast that brings something genuine to every episode. What sets Twelve apart from the dozens of similar shows is hard to pin down in a single sentence — it is partly the writing, partly the performances, partly the way it commits to its premise without flinching. The kind of sci-fi that works on ideas as much as spectacle: that is the shorthand, but it undersells how well Twelve executes on it. An audience of 45 has voted with their time — and their score reflects a run without many weak episodes. The streaming access means you can form your own opinion tonight, without any barrier to entry.

Korean production values give Twelve a feel distinct from American and international alternatives. A group of heroes, each embodying one of the 12 zodiac signs, battles to defend the Korean Peninsula from malevolent spirits. Don Lee and Park Hyung-sik lead a cast that brings real weight to the material. It aired in 2025. The world-building is meticulous enough to sustain multiple rewatches, with details in early episodes that only make sense later in the run. It delivers reliably on what it promises, which is more than most of its competition manages.

Sci-fi fans who want ideas alongside the spectacle will find Twelve genuinely rewarding — it shares something with Black Lightning but carves out its own territory entirely. The kind of genre television that makes you think as well as watch. The premise is strong enough to sustain multiple seasons without collapsing under its own ambition, and the writers have the discipline to ask interesting questions without needing to answer all of them immediately. The complete run holds together as a coherent story, which is harder to pull off in the genre than it sounds. If you have been burned by ambitious sci-fi that could not sustain its premise, this is the exception.
