As a mermaid fan, I think this show is pretty good! It can be cheesy at times, but I find it very entertaining. This is a tween show so it's not that innapropriate. There isn't really violence, though the drama in the show makes it tense at times. There is a good bit of kissing, but it's not really sexual. However, in a few episodes some girls wear some reaving outfits, and sometimes the girls wear bikinis. More romance in season 3. The role models are pretty good; Cleo, Emma, Ricky (and later Bella, who replaces Emma) value friendship and work together. They do, however, lie to their parents once they get their powers, but they're mostly good role models. If you like mermaids you'll probably like this show.
