Just saw the movie "The Big Short" a few days ago. It stars Steve Carell, Brad Pitt, etc. and is based on the book by Michael Lewis.
I thought the topic was an important one, but the movie was not that entertaining. Also, they presented things like CDO's (Collateralized Debt Obligations) and CMO's (Collateralized Mortgage Obligations) in such a way that many probably walked out with their heads spinning a bit. Nonetheless, if their main point was to present Wall Street as a group of unethical and naive people who can be outfoxed by others of more modest means, then they scored big-time.
One other point they missed- they assigned blame to Congress and financial institutions for all the bad (NINJA- no income- no job or assets) loans that were issued in the years leading up to 2008. Shouldn't some of the blame have been assigned to those applying for the loans and lying on their applications???
I also saw the movie Moneyball (which also starred Brad Pitt and is based on another book by Michael Lewis) and that movie was MUCH better.
There are lots of Wall Street movies which are much better than "The Big Short", in my own humble opinion. For instance, Boiler Room and Wall Street (the original one with Michael Douglas and Charlie Sheen) were both much better. For documentaries- the movie Inside Job (narrated by Matt Damon) is OUTSTANDING!
