I watched the movie a few months ago, and I was not pleased with the storyline or the acting. They were very predictable with the acting and they acted very stereotypical for mermaids. I found Siren to be extremely annoying. I also found the rest of the "mermaids" to be more villain-like than heroic. Adam ( Jack Dylan Grazer ) had his rare bone disease, and all Siren needed to do, was give a little bit of her blood to a boy who's condition couldn't be cured medically. I honestly don't see the problem with that. Overall, I know that the actors probably worked hard to make this movie, but it could have been so much better.
