If you want science fiction that respects its own premise, Impulse is available in Australia on YouTube Premium, and in the US on YouTube Premium right now. Across 2 seasons, the show has had time to find its rhythm and keep it. 301 people have weighed in on TMDB, and the verdict leans heavily positive. Maddie Hasson sets the tone, and the world-building does the rest. Start it on YouTube Premium whenever you need something guaranteed to land.

Impulse is not trying to be everything to everyone, and that focus is exactly what makes it work. Impulse treats its concept seriously enough to follow it all the way through. 16-year-old Henry Coles is an outsider in her new town of Reston, New York. With a major chip on her shoulder and no friends, she remains withdrawn and isolated, but everything changes when a traumatic encounter with a classmate triggers something deep within Henry— unleashing a power she cannot control. The human element stays intact thanks to Maddie Hasson and Missi Pyle, who anchor every scene. The series ran for 2 seasons (2018–2019), building a story that gave its audience time to invest properly. The world-building is meticulous enough to sustain multiple rewatches, with details early on that only make sense later. It rarely drops the ball, and when it does, it recovers fast.

Sci-fi fans who want ideas alongside the spectacle will find Impulse genuinely rewarding. If you have already watched The Outpost, Impulse is a natural next step. A contained run means every episode is doing real work. Maddie Hasson 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.

Impulse was cancelled in 2019, created by Jeffrey Lieber — and 2 seasons are available to watch from start to finish.
