TVwimb- Here are my current recommendations:

[KACB]

Chicago PD- A little above your standard cop shows
Southlands- Just re-watched the final season, Superb.
Gomorrah- Subtitled mafia drama based on the book. Good start.
Vikings- Historically inaccurate but gripping

Gotham looks good and the Walking dead is back in October.

[One Wilf Copping]

Banshee or Sons of Anarchy. The same format just different situations.
