I get the fact that Martin Scorsese needs to move on from the Mafia to a new generation of criminals, which explains “The Wolf of Wall Street” (2013). I’m just not sure what I was supposed to get out of this movie. It’s voyeuristic fun watching the decadent rise and unsurprising fall of pump-and-dump stock millionaire Jordan Belfort, as played by Leonardo DiCaprio. At several points, however, we’re fed the notion that Belfort was somehow helping everyone else while he was helping himself. That’s just typical self-serving sales bullshit, but not surprising. A salesman’s first priority is to sell himself.
