Harmony

Similarity: - Dystopian that look like Utopian-world. - Main system that adopted in future (Watchme and Sybil). - Both protagonist feel the world work is wrong and their occupation is similarly same (Investigator crime). - Some bloody incident. Dissimilarity: - PP have more action than Harmony. - Harmony is more philosophical and heavy description about brain thing.  

Similar thematic elements, psychological elements and dystopian settings. Use of literature throughout. Antagonists are very similar in many ways. Both left me wanting more of the world I'd just seen, wondering what comes next. 

Two of my all-time favorites. Both of these take place in a dystopian society where the masses fail to either notice or care about how completely they are controlled. Our main characters see through their utopias and recognize truths that eventually come to undermine the systems that the societies are built on. Both are serious, dark, unpredictable, and try to tell a more intellectual story to communicate strong themes about the future that we might be facing in our own world. If you’re a fan of one, give the other a try (especially Harmony because it needs some well-deserved love). Though Harmony almost certainly drew inspiration from Psycho Pass, it’s still extremely unique and original read more 

Like Harmony, Psycho-Pass is a more serious-natured series set in a futuristic setting where humans are implementing a type of governing system in the attempts to create a peaceful, utopian society. However, there will always be those who do not agree with "utopian standards", as well as those with secrets and/or alterior motives - as both titles well portray. On a side note, the main protagonist in both Harmony and Psycho-Pass is a young woman. 

Both essentially their own genre a philosophy essay. Purpose of any philosophy essay is not give you answers but give you questions. 

Two anime exploring complex philosophical themes, free will and suicide as it's ultimate expression in particular. Both use a criminal investigation by the protagonist, who works for international law enforcement, as a framing device. Both take place in both Japan and other countries (even continents) due to the international nature of the mystery conspiracy. Both have an antagonist who may or may not be supernatural and has similar powers over the mind of other people, yet neither anime has a respective tag. Both have a similar, half-open ending and conclusion to their subject matter. Babylon is more heavy handed and story driven, where Harmony is mainly a character drama and dialog savy. read more 

Freedom, privacy, being human. How much are you willing to trade in others to be happy, will you trade the very thing that makes you human in order to protect yourself or will you sacrifice everything you have including your life in order to protect your humanity. Both movies touch on the subject of freedom and the "old as world" existential question. Seeing two representations of the hypocrisy and the "plastic" facade that we as a society put on every day. The movies offer two different points of view and answers to the same problem. For any Project Itoh fan, I can say that both movies are two different sides of the same coin, marking the struggle of a man fighting cancer and his acceptance of the inevitable end. read more 

Both films have the central theme of a person's conscience and what it means to be human. Both set in a dystopian future with strong female leads and a plot that is sure to make you think. 

Both emitted similar feeling and emotions to me. If you like Harmony you sure have to like Ergo Proxy too and vice versa.
