I'll begin by stating this final episode does not tie up a number of loose ends. Did Covid impact production. Did the author tire of his creation?
Rocco spends much of the time hospitalized but is driven to help the hospital avoid a costly law suit.
We see a lot more of Ugo Casele, and Antonio; we will shake our collective head at the choices one member of the team will take. Love or its facsimile hits two or three couples. There's even closure for the boys from Rome. Rocco becomes a little less irritating because he owes his faults.
Were there a fifth novel or a season 5 I would welcome the arrival.
Cheers!
