About this show

Siren takes us inside Bristol Cove -- a coastal town 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.

From the very first episode I was honestly hooked... I absolutely love this small lil series... They truly couldn't have done a better job. The actors were perfect fit. Im so sad it didn't do better...I think this show was under estimated from the beginning . I bet if only they had marketed the series a lil better this series could have been a real hit. A huge money maker. . I promise you'll fall in Love from the very start and the further in the deeper the hook.

Great Serie, I love it it’s only difficult to watch it I couldn’t rent it on play Google here in switserland for 1.99$. These regulations are terrible The tension is great and also the message to the world they want to give us. Everybody knows that “ the ocean cleanup “

Something different about sea life and mankind. Not gore or someone killing people completely. Looks as though trying to bridge the gap and correct wrongs of the past, but telling a story...unveiling story of past and with closer study evolution is unveiled but things to look forward too in the future to come. Exciting and intriguing.
