Reception
Ergo Proxy received mostly positive reviews, with critics praising the series for its intricate visuals, cyberpunk aesthetic and intellectual themes; while criticizing the uneven narrative and its over reliance on philosophical references. Newtype USA stated that they were "excited by the premise of the show, which features complex drama surrounding the strikingly beautiful crime investigator Re-l Mayer, and an intricate sci-fi setting, incorporating robots, living in human society and a grotesque array of unique monsters". Newtype went on to praise the "tremendous supporting cast and carefully woven plot".[28] Newtype USA featured the first Ergo Proxy DVD in their "DVD of the Month", describing it as a "show that rewards viewers with a deep, believable, and above all thoughtful sci-fi story instead of simply bashing robots together".[29] Katherine Luther of About.com praised it for its cyberpunk themes and mix of 2D and 3D animation as well as its deep psychological storyline, calling it creepy, intense and "edge-of-your-seat-delightful".[30]
THEM Anime Reviews praised the visuals and pacing of the plot while noting that the greatest flaw in the series is that the designs can be inconsistent at times.[31] Zac Bertschy of Anime News Network gave it an overall score of B+ and criticized the characters, stating "It's an unfortunate stain on an otherwise excellent series." However, he praised the animation stating "The backgrounds in particular are breathtakingly detailed and beautiful, which is a surprise given the bleak, dystopian surroundings"[32] Carlo Santos, also from Anime News Network, criticized the middle and ending of the anime, stating "Some of the middle episodes fall back on experimental gimmicks and fail to advance the story, while the finale becomes a towering mess as it desperately tries to resolve every single plot point. Even the animation has embarrassing moments of inconsistency." However, Santos continued to state "for trying so hard to scale the heights of a difficult genre, Ergo Proxy still deserves credit. It accomplishes more than most other anime series ever hope to, flaws and all."[33]
IGN contributor D. F. Smith reviewed the series DVD box set in 2008, giving the series a 7.0 out of a possible score of 10. Smith overall found the visuals, music and voice acting of Ergo Proxy to be exceptional, but stated that the overall story was too complex and relied too heavily on philosophical references rather than a strong narrative. In conclusion, D. F. Smith wrote "Ergo Proxy isn't without its share of disappointments, but even so, it has a heck of a lot going for it. What it lacks in the way of a truly gripping, involving story, it makes up for in part with a powerful soundtrack, some powerful visuals, and the occasional powerful insight. If those are the sort of things you go to Japanese animation looking for, you might not find this series disappointing at all".[34] Another IGN columnist, Ramsley Isler, placed Ergo Proxy's opening as the 10th greatest anime opening. Isler praised the opening's use of dark visuals juxtaposed with the opening theme song's optimistic tone, comparing it to a Nine Inch Nails music video.[35]
On June 12, 2015, the Chinese Ministry of Culture announced that they had listed Ergo Proxy among 38 anime and manga titles banned in China.[36]
