The series follows the city of Bristol Cove, where suddenly a mysterious girl appears from the sea telling that she wants something from the sea and people of the city must help her.
The characters have strong personality traits, and they feel like fully formed people with different driving forces that make sense. It is so easy to reason why each of them does what they do, and it has only been two episodes.
Everyone wears their heart on their sleeve and by god they are trying as hard as they can to deliver the premise...Siren is worth a look for anyone craving their next YA fix. It's not the best the genre has to offer, but it's far from the worst.
The show has successfully turned those beautiful mythical creatures into something far more dangerous than what we typically see, and it seems to be going in all the right directions because of it.
Perhaps like the amphibious fish that grew legs, the series could evolve into a fully realized something... anything. But as it stands, it's best to resist Freeform's "Siren" song or you might find that you'll just want to throw it back.
