The second season of the American Crime Story provides insights into what could have been the thought process of the killer of Gianni Versace.

Andrew Cunanan is played brilliantly by Darren Criss, who shows his pathology as well as patterns of abuse, violence and inclination towards crime, to justify his ends.

Gianni Versace is portrayed aptly by Edgar Ramirez, his disenfranchised partner Antonio by Ricky Martin and formidable sister Donatella by Penelope Cruz.

It is a heavy and dark series with little respite from depraved and selfish acts, but it is a slice of history which should be contemplated.
