I'm looking for an anime that has dark elements to it, possibly horror, and a good/interesting plot.
I really liked the fma manga (not so mucht he animes I found them both lacking in different areas), and I found higurashi absolutely amazing, as I did elfen lied, death note, and code geass. (these aren't the only animes I've watched but I'm looking for one that has similar characteristics to some of those. I also don't like mechas I only like code geass because I found the story phenomenal and it didn't focus too much on the mecha side of it).
So anyways any help or suggestions would really be helpful because I am really trying to find a really good dark/horror anime right now. I don't know I guess I'm just in that "mood".
