Psycho-Pass, Double Decker! Doug & Kirill Recommendations
Both are about police in a futuristic setting. Psycho-Pass, however, is waaaaaaaay darker and thematically relevant to the average viewer, rife with messages regarding free will and existentialism.
Alternate recommendations for those who like Double Decker that MAL are not showing (for some reason) include Ghost in the Shell: SAC and Heat Guy J.
Both have the same action sci-fi and police genre, but while the other was more of a darker theme the other one was more like a semi comedy theme, but when it come to the characters attire , you might say that one has their characters dress in a very sissy attire while the other had their characters dress simpler.
