Did You Know?


The first several episodes of the show feature establishing shots along the coast with a very red sun and smoke filled sky. These scenes would have been shot during July and August of 2017, when wildfire smoke from the B.C. Interior drifted southwest to the Lower Mainland/Washington state area. See more »

User Reviews

Surprisingly good!
4 May 2018 | by richgibbonsSee all my reviews

Ok, so you have to suspend a bit of belief to get into it, and the program certainly benefits from you being in the mindset of - "ok, I want something sit down and switch off now". But with that said, Siren is highly enjoyable.

The pacing is just right, and acting is decent. Especially that of lead actress and primary 'mermaid' Ely, who does a great job of drawing you into her otherworldly nature. She's definitely a fantastic choice for the role.

I'm two episodes in and can't wait for the next one.
