When The Big O first premiered on Cartoon Network's Toonami, I dismissed it as being "just another mecha show". It wasn't until it aired on Cartoon Network's Adult Swim that I actually sat down and watched the entire series, realizing how great the series truly is.
At first glance, Big O seems like just another giant robot show. However, if you dismiss it, like I did, you will be missing out on one of the greatest animes I have seen in a long time. In fact, it is very different from many mecha series in that each episode plays out as a sort of mystery, making it popular to compare this series to the animated Batman series.
The story of the series is very dark, telling of Paradigm City, a metropolis much like a run-down New York, where every inhabitant lost their memories 40 years prior to the events of the series. "Memories" have become precious commodities in the "city of amnesia". Fragments of these memories are the Megadeus's, giant robots that seem to have minds of their own. Roger Smith, the show's protagonist, pilots one such Megadeus, the powerful Big O.
The story may be dark, but the characters are certainly colorful. Roger Smith is a negotiator (think private investigator) who pilots the Big O. R. Dorothy is a female android who becomes Roger's sidekick and maid. Beck is a small-time criminal who seeks vengeance for Roger humiliating him. Many more characters appear and play important roles in the series.
The animation, voice acting, and musical score are supurb. The animation is very fluid, but the colors are often drab but help to convey the mood of the series. The voice actors all do an excellent job, and they may be familiar to the avid anime viewer. The music is epic and helps to draw you into the show. The opening theme is somewhat strange, but I grew to like it over time.
All in all, Big O is one of my favorite series ever. I wholeheartedly recommend it to anyone who enjoys giant robot anime or just anime in general.
