For a trading/banking series it shows very limited scenes explaining how they make money and do deals. You may need subtitles if you have trouble with foreign accents at times.
After watching this series it makes me appreciate who good Billions is written and edited, easily twice the show. More complex story lines and you care about the characters even if you don't like them. In this series there is nothing memorable.
It had so much potential, the lead actor will hopefully be recognized and put in something worthwhile soon.
