This is an epic story that is beautifully drawn and designed. It is very dark and more than a little depressing, but mostly it is emotionally involving. There are a lot of anime characters whom I could calmly watch being dismembered -- because I don't care about them. But the characters in Gilgamesh are emotionally engaging. I believed in their stories, and when they felt pain, it was a big deal to me. In feel, it's a bit like Texhnolyze. Ergo Proxy has some mood similarities but is a very different show. In visual style, few shows come close.Perhaps Witch Hunter Robin is a rival for visual beauty.
