Unfortunately, any time an artist portrays a culture in a way that's ambiguous it has to be left open to interpretation from those who are going to take the opposing view- that it glorifies what's being portrayed. In this film, we are essentially treated to a three hour romp of orgies, drugs, and outlandish recklessness from Jordan Belfort and his cohorts, and it's they who revel in their money, toss it away, spend their time in a constant state of drug induced euphoria and clearly treat women as objects to be used and humiliated. If people are appalled by this behavior, that's probably a credit to their own morality, as I'm sure there are wannabe bankers who will seek to emulate it, just as Scarface's Al Pacino stands as an icon to a whole generation of gangsters and rappers (in other words, those who missed the point). But at the risk of attracting that crowd and in order to make a film you can sit through, this is all treated as a black comedy of the highest order, and Leonardo Dicaprio gives what's arguably the greatest performance of his career.
He certainly gives the role everything he's got, and commits fully to the drug crazed, narcissistic Jordan, who enters Wall Street at age 22 and about two seconds later is immersed in the manic, alpha male lifestyle, with Quaaludes and hookers his vices of choice. It's a hilariously committed, very physical performance that has him doing things on screen you probably never thought you'd see him do (the final Quaalude scene had my theater in stitches), and he's joined by Jonah Hill in a slyly funny turn of his own as his weaselly little pal Donnie. The movie itself is basically three hours of debauchery that, while entertaining, does grow tiresome after a while, although it can certainly be argued that depicting excess in an excessive manner is the point of the whole exercise. But I think that the film could have shaved 45 minutes off its running time and still made its point in style.
