Great series about the 1920s prohibition era Mafia and gangsters. Many historical figures mixes well with fictional characters in this series i.e. Al Capone, Charlie 'Lucky' Luciano, Meyer, Arnold Rothstein, Johnny Torrio and many more.
The show is 'slow burn'. Very slow at the start of the season but every season explodes near the end and it makes it so much satisfying to watch. Recommended.
