This could have been so much better (been said about a lot of films) and I started off thinking I'd sympathize with these women but in the end I was thinking the justification for drugging and robbing people was that they were part of the cause of the crash of 2008 - no!
It's certainly not a substitute for my anger that the US justice system failed to bring anyone to account for the crash - something they make a big point about. If I had seen some guilty party getting their comeuppance It would have made It more emotionally satisfying. We do like to see a film villain and we do like to see them punished.
So it may be that I found that there was a failure on the part of the film to give us a character who served as the embodiment of the financial evil doings of those days and for these newly empowered women to be angels of vengeance. Instead its a disappointment when they are punished and the world doesn't change.
