The quality of the actors, dialogue and story-line is variable. Where the strong actors are given their opportunity to act well they do so in a very believable way, absorbing and enjoyable to watch. They carry the slight and occasional weaknesses in the plot and dialogue and make the show quite watchable. If you are less critical with some of the actors who are not quite as convincing in their roles you will probably enjoy the show. The story tells a tale of the children born of a combination of man and siren, the tidelanders, and the role they play in a small coastal town's ways of making money. There is subterfuge in the human part of town, subterfuge amongst the tidelanders, and all hell between humans and tidelanders despite their strong reliance on each other as part of a production line "product" they make. Some good plot points, some unoriginal well-tried plot-lines done with very little new material, but overall the broad story is original and well executed. Worth watching, and will probably produce a second series. Also, my thoughts are a second series will probably be really cheap to make , not all that many of the first series cast left by the end of it all mayhem and carnage. Not a series for kids.
