If you're looking for an anime about cute mermaid girls doing cute things and can put aside the fact that physics will break in this and the mermaid aspect is nothing more than a reason to put tails on girls and have them float around, this is right up your alley.
I'm not sure what happened with the earlier episodes but both the sound and animation was incredibly mediocre early on. Around episode 4 this series started to up the swimming cycles in animation and also added more SFX that makes you "feel" like your underwater.
The story line is rather generic, just girls going around and some vague idea they're working towards along with some hidden potential plot that reveals itself later
Static visuals and backgrounds are absolutely gorgeous even if the character designs leave a bit to be desired and at times the animation itself feels lazy.
This isn't a fantastic anime, it's not a great anime either. It's a good anime that's cute and one that's not deserving of the harsh criticism it's receiving. After having now finished the anime, this anime is one you must give a chance if you're a fan of all things cute.
