I saw 'The Big Short' in the theater this week.  Very interesting insight into the `2008 real estate bubble pop, the sociological factors leading to the creation of the bubble, and the type of thinking that leads to the identification of the bubble before it popped.
Greed seems to be the fundamental human attribute that lead to this economic problem.
An interest in truth seemed to guide those that determined the existence of the bubble.
I felt the movie was well acted, fairly well shot, compelling, and even funny at times.
I recommend this movie.
