A little bit of Information on why they couldn't continue.

A fan asked for Joe Menndez because the series Siren has been cancelled!!

Fan: Why was Siren cancelled? It was the best and best evaluated!

Joe Menndez: the answer is somewhat complex and frankly it won't be satisfying to anyone. Essentially it was a business decision. Although it was technically the highest ranking program for Freeform, there was a significant drop in rankings compared to previous seasons. So how much it cost the program to make and The Return they were getting, it just didn't make sense. That's the deal, it was just that.
