Gave up on the series quickly during season 2.
On the one hand, all of the concepts I wish I had seen in H2O appear in this show: we get to see mermen, some mermaids lore and magic, mermaids who turn to humans instead of humans turning into mermaids, a mentor figure for the trio of mermaids, and while those elements felt alright, I felt the quality of the writing faltered. The characters and storylines were uninspired and convoluted, especially with the antagonist at the end of season 1 almost entirely forgotten about later on. For me, it was a letdown and if you liked H2O, you may not like it as much either.
One positive I have to bring up, strangely enough, is I prefer the blue tail for the mermen over the orange tail given to mermaids as it's a nicer colour in the water.
