Well-made. But I personally hate to see an unjust protagonist succeed in life. I wanted to watch the diabolical, lying, disgusting MC get punished. However, realistically, the evil wins and the innocent people die, which was intolerable to watch.
Some would interpret the movie as encouragement for doing inhumane, unforgivable things just to get money. I gave it just one star for making me feel bad for the innocent people and for leaving me angry at Jake Gyllenhaal. Great movie otherwise.
Moral of the story: Don't trust anyone at your workplace (they could possibly NOT hesitate to get you killed)
