The characters appear unusual at first; perhaps even unlikeable. But there is a reason behind this: in Romdo, the futuristic, domed city that is humanity's last means of survival in a ravaged, post-apocalyptic world, citizens are not allowed to show emotion. To show emotion is to understand that something is wrong, and that can lead to questioning yourself and your environment. "Doubting the system is bad. Always obey." Those are the rules one must follow in order to be a Fellow Citizen. However, Re-l, Vincent and Pino soon lt their emotions overcome them; they see Romdo's flaws and lies for what they really are and confront them with their only weapon being the truth. However, lies make people happy. Can they really handle the truth?
This show is deeply philosophical, especially concerning Vincent's inner turmoil and struggle. He is forced to see that he is a man with no past, a man who wears the mask of one who would deny his own fate. His road to self-discovery is deeply felt by the viewer, and the moment he realises the truth is one of the show's climaxes and brilliantly conducted.
I don't want to spoil anything else, but if you're a fan of philosophy, musings, and conspiracy theories, as well as watching characters grow, mature, and fall from grace or rise above it, then this is the show for you. All the information is slowly revealed, and sometimes revealed from the get-go--you just don't realise it until you've connected the dots or seen its conclusion.
I highly recommend it.
