The first season’s posters were amazing as well (http://www.dramabeans.com/2017/03/detectives-spies-liars-and-new-hires-in-poster-parade-for-spring-dramas/) but very different: moody, cinematic, very noir and femme fatale. I like that for this season they go full buddy cop influence, which highlight the new relationship of the two main characters. And the humor, ‘coz that is a fun bickering couple!
