People took it a step further on Reddit, with one saying: ‘Excellent documentary on the Mafia in Philadelphia in the 1990s.’

Someone else wrote: ‘As a 3rd generation native Philadelphian, I’d say very authentic description of the culture of South Philly and the FBI, with whom I’ve had the pleasure of being personally acquainted when they were investigating a business I was working for in the 80s. Definitely worth watching.’

The Asset first hit screens earlier this week, after an immense build up for the tense series that was first teased in an trailer in early October.
