I was enthralled by the narrative and I thought that the performances were fine. The editing, cinematography choices, sound design, etc. were interesting but more distracting than anything. Worst offense though is the third act. The ending of the film was really weak. 

I thought they did an amazing job building up tension and animosity toward the short investors and even had me wondering what the hell was gonna happen because the banks were lying about the performance of their investment. Then it just kinda cuts to the future and all the sudden they have their money? No big reveal, no dramatic realization, no pay off. It was a humongous let down and it was the part of the film I was looking forward to the most.
