I finished watching H2O yesterday ^_^
so here's a review!
This anime feels very close to ef - a tale of memories
(which has a new season currently airing, got to take a look at that one later :D)
It's based on a eroge, which shows quite much throughout the series,
yet like with ef, I found the characters are really interesting.
the sad part is, if I'd describe what I think makes them interesting
I'd also spoil it alot >.<
I can say as much as they all have interesting backgrounds without spoiling atleast, and while the music and animation wasn't as good as ef-memories the story was really gripping me in very much the same way.
"After a series of unfortunate events, the young Hirose Takuma was rendered blind. In an attempt to reverse his condition Hirose moves in with his uncle in a rural village, and upon his arrival he quickly begins to make new friends. However, Hirose soon discovers that one of his classmates, Hayami Kohinata, is being harshly bullied by her peers for reasons that neither she nor anyone else wants to explain. Even the seemingly honest and gentle Hinata Kagura, who had been doing her best to be friendly and helpful to Hirose since his arrival, acts harshly towards Hayami. Once a mysterious girl bequeaths Hirose with a life-changing gift, he takes it upon himself to help save Kohinata from her loneliness while working to uncover the truth of the situation."

I guess you could describe it as a mix between ef-memories and higurashi, but with much less gore and psychos.
