Princess Tutu. No, really -- the name is utterly retarded, but doesn't reflect the quality of the anime *at all*. I'd say it's easily one of the best anime I've ever seen. It's intelligent, moving, well-written, and never NSFW or even slightly slutty. It's more like stepping into the world of Brothers Grimm than into what you'd expect from an anime about a magical girl called Princess Tutu. And it's really, really awesome. At the very least, anyone who wants to experience anime should give Princess Tutu a try.
