In my humble opinion, this is nothing short of a masterpiece. Often, I feel that animation (western and Asian alike) tends to forget its roots - the fantastic, the stuff of dreams and imagination. Instead, a lot of animation tries to mimic reality, which many do well. This anime however, tells a playful, dreamlike story, taking you through literary eras without the need to actually jump in time, and as effortlessly as turning the page of a book.
In short, this anime has a strong theme of storytelling, classic fantastic literature, and "history" rather than "legend". The setting is in victorian-like castles, huge libraries and secret corridors, with sudden leaps into the modern big city life, musty basement-bookstores, a desert town, a high tech military base, and more, all blending seamlessly, magically. The characters seem too fantastic to be real, but at the same time they are rooted in historical characters.
I can't even comment on the animation or the sound. It's simply impeccable. But the true strength of this anime, and the final push towards a full 10/10 is the story, and the way it's told. A less-than-great attempt at such a diverse setting and cast would most likely fail, but incredibly Read or Die pulls it off. How the creators managed to do this, I cannot comprehend, but it works! You're seduced and taken for a ride through worlds, eras and genres, from fantasy adventures to street-level action, unexpected character dramas to huge scale crime fighting. It's no wonder that this anime won best OVA at Anime Expo 2002 - I can only say that it's well deserved.
