Working in a similar field I can confirm that these kind of activities and the difficult dilemmas they pose for compliance staff are all too common.

I found the series a great binge watch, with entertaining if predictable plot turns and excellent acting.

My main criticism is that while virtually every male is portayed in a negative way (dishonest, greedy, sexist, weak, alcoholic, bullying, unpleasant) all of the several female leads are honest, caring, likeable, intelligent and downtrodden. This blanket approach to characterisations is very obvious and becomes tiresome quite quickly. A little more balance between the sexes would have been appropriate.
