Seto no Hanayome has grown to be one of my favourite anime over the years. This is mainly to the fact that music has a large part in it, along with songs and great humor. There's a limited amount of ecchiness, which is overshadowed by the sarcastic remarks of the characters and an entertaining episodical plot.
While the storyline of the anime has a less visible or original background plot, it is certainly not one without merrit. Being able to follow the developing love story of the two main characters is both rewarding as well as funny, while they are both tossed around in the realm of mermen, but a yakuza group too.
The voice cast was skilled enough at giving the various characters life, even though the anime may lack the focus of the manga, the voice actors made sure that no character was placed in the rear mirror.
The ending is a classical happy-ending that clearly resulted in a battle for life and love, concluding the anime with grace and a fine comedical finnish.
