There is a modest SPOILER in this post.
After thinking so more about Wall Street: Money Never Sleeps (and getting more annoyed), I have updated my first assessment of the movie.
The screenplay keeps raising the issue of moral hazard (whether to bail out people from the consequences of risks that they knew they were taking). Yet, at the end, the two flawed main characters each get exactly what they wanted at the beginning of the film despite making risky or evil choices throughout. The movie’s payoff (things turn out OK no matter how badly or foolishly you behaved) is exactly opposite of the movie’s sermonette.
Pretty lame, Oliver Stone.
