Plot and characters pretty weak
The plot wasn't very interesting. It's revealed in the opening that the collapse is happening and everything from then on is just played very straight. The actual "margin call" to sell off everything was made before the movie's halfway point and it was no real contention or internal struggle. The last half of the movie is just about various characters reflecting and contemplating on the collapse - through various characters that are pretty interchangeable. Everyone seemed to know exactly what was going on though, no one were confused and no one had any personal revelations.
The young trader (spock) seemed like the protagonist you're supposed view the story through and identify with, but he is only there to crack the code (done in the first 30 minutes) and present the information to the higher ups.
Sam (Kevin Spacey) was just there to complain a bit and cry about his dog, no real character arc, didn't really even fight or present a case against selling.
It had good actors with hints of interesting characters but they didn't do anything with them - no conflict or personal struggles, no scheming, no big presonal revelations, no arcs, no plot twists or reveals. Pretty strange considering the collapse was very confusing to a lot of people and not many understood what was going on as it was happening.
So I'm open to hear other opinions. Did you like it? What made it stand out for you?
