I watched this anime recently and was pleasantly surprised. First thing noticed was the animation quality itself, which was a LOT better than in some of the animes I've seen (10/10). The music was also really nice (especially the opening theme, "Scarlet")-- well, maybe except "Cross My Heart" (8/10).
The characters were mostly well developed - from lonely Toya to ruthless Kagami to compassionate Yuhi. The only slightly annoying thing was Aya's tendency to go over-emotional... Overall I'd give character design a 9/10.
But the best thing was, of course, the storyline itself, which was impressively well developed. Although tragic and cruel, it shows how important it is to love and be loved, to feel compassion and to have a family. Perhaps the only drawback to it was that in the first few series, Toya and Aya's relationship got sort of rushed. Although after watching the anime "X", which pretty much had no storyline at all to it, I feel obliged to rate the story of "Ayashi no Ceres" as 10/10.
Beware! "Ayashi no Ceres" contains many very cruel and nasty scenes which are NOT suitable for children.
