It was a story about humans and human nature, defects of the legal system, morality and family relations.
"The blood is thicker than water."

A play of expressions and symbols.
The camera work was beautiful; it struck me in the very first episode.

The characters were complex and well played out.

Music really amazing not only as a use in the story, but also a in itself.

Overall, one of the best ones I've watched.

It reminded me a bit of Twin Peaks.

As in:
A new cop goes to a weird small town, in which everyone seemes to have secrets.

I'd say Beyond Evil and Twin Peaks cross eachother somewhere, but are going elsewhere.
