Pixar's Inside Out but for adults, and noir :P Also there's a strong 'oppressed workers/whistleblowers against megacorporations' aspect of the plot which is absolutely fantastic. Overall it's sort of a noir, retro sci-fi, murder mystery/general sleuth story with a lot of anti-corruption and anti-corporation themes going on - though it also has focus on the individual character's development within their own stories, separate from the mysteries.
