There's much debate among anime experts as to what this series actually means. Several weeks after watching the complete collection I'm still turning it over in my mind. It boldly takes on philosophical themes such as 'consciousness', 'personal identity' and 'time' itself. Even has the cheek to name a few of its characters after modern philosophers - Husserl, Kristeva and Lacan. Some will find this dreadfully pretentious, but I can't help admiring the ambition of the creators for coming up with such a thought-provoking work, even if the convoluted plot does leave me feeling somewhat baffled. The visual design is well-judged: pleasingly muted colours which are much in keeping with the dream-like aspects of the narrative. Likewise, the mostly ambient soundtrack is another notable achievement. If you like a plot that slowly evolves and characters that keep asking themselves 'Who am I?', then Ergo Proxy will keep you intelligently entertained for hours.
