Take a city with an architecture heavily influenced by neo gothism and art deco. Take a dapper, tall and dark main protagonist with detective skills and two aliases, driving a huge and powerful weaponized black car and with pockets full of gadget. But this it is not Batman the animated series. Take a giant robot with a retro design, take a pilot who summon it by talking to his **** who yell the name of the attack he uses. But this is not Giant Robot. Take an emotionless young women, a conflicted hero looking for his past, a city shrouded is mysteries and strange gigantic metal beasts attacking civilization. But his is not Neon Genesis Evangelion. Big O is at the confluent of these three monuments but manages to have a very personal style and approach and not changing tropes into cliches. Aesthetically it is very close to the Batman TAS first seasons, partially as an homage and partially because Sunrise, the studio behind Big O, was patronized by WB to work on the monument that is the early 90s' Batman series. That means also that it might help the more allergic to the "Anime style" to enjoy that show. The episodes are mostly stand alone but are still linked to the main plot of this animated series: why all of the inhabitant of Paradygm City lost their memories 40 years ago and what other wonderful technology from the past is the cause of this.? The overall quality of the scenario is good and really hooking thanks to Paradygm City and its mysteries. The main character, Roger Smith, the best negociator of the city, and R Dorothy, the snarky android who accompany him, are a wonderful duo. The conflict of their divergent point of view and behavior is the main fuel of the show's humor. The rest of the cast is also worth mentioning too, a series of well used tropes like Dan Dastun (the commissioner and Roger Smith's "friend" who doesn't know about him piloting Big O), Angel (The vixen/spy who allegiance isn't clear), Norman Burg (Roger's Butler/cook/mechanic) and Alex Roseberg (the main antagonist, a megalomaniac billionaire who owns most of Paradygm City). Technically, and for an anime from the late 90s' early 00s', the animation is really good. There is a great used of really cinematic shots and plans. The background are full of wonderful details and personality despite the dominant grayish colours. Aside of the first opening song, a very pale copy of "Flash Gordon" by "Queen" that doesn't really suit the show, the score is mainly composed of Jazz and electronic jazz music during the exploration or inquiry parts of one episode with a much more dramatic classic score during the robot fight. It works rather well and the soothing Jazz adds another touch of coolness. To sum up my feeling over Big O it a gem that is a bit too much overlooked, mainly because it doesn't look like an anime and because it doesn't feel like a 90s' US animated show but that would be a mistake. Big O is simply a good show, no more, no less and should be seen as this
