10 out of 10 for eye candy....
This was a light-hearted, simple anime, but one that had a well-developed enough story to support itself. It was humorous without being overly silly or illogical. Not a masterpiece, but I would still recommend it. There are a lot of flashbacks, so if you don't like that then maybe this isn't the anime for you.
The animation was standard to slightly above average. I appreciated that the musculature on the characters, while very well defined, was not too bulgy or unrealistic. It felt like the approprivate amount of musculature for a group of swimmers. The music, while not phenomenal, was pretty good.
