This anime will doubtless divide opinion. Some will find its violence and nudity excessive while others will find them in keeping with the plot. I'm of the latter opinion, and the erotic content (mostly of a lesbian orientation) and the sadistic violence are key elements of the story and therefore never gratuitous. The story draws on Greek myth for its inspiration, though is set in modern Japan over the course of 60 or so years. Rin, the heroine, is an immortal detective who gradually uncovers the secrets and mysteries of her immortality across the 6 episodes. She is a quirky blend of the nerdy and the voluptuous, depending on the circumstances, and a very likeable character. Her sidekick, Mimi, another immortal detective is also likeable and the banter between the ladies is witty and entertaining. Some of the playful humour and the sudden shifts in narrative tone, from cute stuff to violent stuff, remind me of Elfen Lied. Stylistically, Rin Daughters of Mnemosyne is not state of the art CG animation, but its design has an unfussy beauty with impressively bold coloration. This edition is anamorphic widescreen. The extras (interviews with voice cast) are absolutely useless and an interview with the director would have been a lot more helpful. But, of course, the film is the thing, and if you're looking for an engrossing anime that is eccentric and different from the herd, then this is well worth investigating.
