Ocean Waves might just be the most realistic anime I've watched, or close to. Or the most realistic slice-of-life. Either way or both, it's so realistic that it boarders and crosses the line to Mundane County, which is both a good and bad thing. It also means that it's slow, real slow. But that slowness adds to the mundane, also a good/bad thing.
I didn't care much for the music and I had no problem with the VO's, but I am a fan of Studio Ghibli, so the animation struck a good note for me. It's the usual fare and it's comforting that it isn't different, but it might be a problem for some for it not changing.
The characters are normal and aren't particularly special and it has it's own double-edged blade in that. But if you need a romance fix, this might take care of it; if you don't mind a slow ride through the country. It's pleasant, but even now I'm unsure if it'll leave a lasting impression on me months from now.
