By this point in the Psycho Pass series it's a different feel. You don't get the masterful story telling and moral dilemma of Season 1. You get a better total story if you combine Season 3 with the First Inspector movie compared to Season 2. Season 3 Psycho Pass is more of the cat and mouse game type of story with a lot of different characters doing different things to advance the story. The reason for mixed reviews is that it doesn't have that masterpiece plot that Season 1 had. It is also difficult to match arguably one of the greatest villains in anime historywith the villains in the later Seasons. So they went for action and detective work.

I like Season 3 because this is what I always imagined what Season 2 would be. I actually liked Season 2 until they jammed everything into the messy ending. The artwork is amazing as usual. Characters from Seasons 1 and 2 have supporting roles and cameos. The end of Season 3 allows for a possible Season 4.
