The theme song says it all "shuai dao fen shou" (handsome until we have to breakup) -- a thoroughly amusing and addictive simple plot of prince and (childhood-first-love) fishing-village mermaid, who mysteriously can't swim... the side characters lend depth to the storyline too.

the leads and swim teams had great acting and humorous lines, but for me it was the convincing scariness of the Fei family that stole the show.

Minor spoiler: the opposing team's "black" coach was also quite scary, but she turns out to be a fair, reliable ally in the end.
