Siren is currently streaming in Australia on Disney Plus, and in the US on Hulu, and it earns its premise rather than just borrowing genre trappings. 3 seasons means there is plenty to get through without ever feeling padded. With 3,423 viewer ratings on TMDB, this is not a title flying under the radar. Eline Powell sets the tone, and the world-building does the rest. There is no real reason to keep putting it off — it is right there on Disney Plus.

There is a reason Siren keeps coming up in conversation. The world-building is meticulous, but it is the characters who carry Siren through its more ambitious moments. The coastal town of Bristol Cove is known for its legend of once being home to mermaids. When the arrival of a mysterious girl proves this folklore all too true, the battle between man and sea takes a very vicious turn as these predatory beings return to reclaim their right to the ocean. Eline Powell and Alex Roe lead a cast that keeps the bigger ideas grounded in something human. Across 3 seasons (2018–2020), it never lost the thread that made it worth starting. The rules of Siren's world are consistent enough that the big swings never feel like cheating. The hit rate here is high enough that skipping ahead never feels like an option.

For late-night viewing or a proper weekend binge, Siren fits the bill. Once Upon a Time in Wonderland is the obvious comparison, but Siren earns its own place alongside it. A contained run means every episode is doing real work. Eline Powell grounds the bigger ideas in something human. Once you are in, you will want to talk about it.

Siren was cancelled in 2020, created by Dean White, Eric Wald and Nick Copus — and 3 seasons are available to watch from start to finish.
