Leo saved what would have been an otherwise terrible movie. We never really got a sense of what they actually did. They spent so much more time on the drugs, hookers, and long speeches and hardly any time on the actual substance of his life, how he was making his money. Even the FBI investigation, they didn't spend time on what the guy was being investigated/convicted for.
The ratio of time was like 95% on hookers/drugs/boiler room speeches, and 5% on what he did and his life.
I think that was the whole point...There were various points in the movie Leo would be speaking to the audience about some aspect of wallstreet and then midway through the sentence just retract his statement and go on to talk about the parties, the drugs and excess. This movie wasnt about how to make money, but more like what you can do when you make money.
Here's the thing though, they had plenty of opportunities to add more substance to the film but for example they spent like 30 minutes on the lemmon scene that just dragged on and on. They could have developed his relationship or lack of relationship with his wife/kids. They could have delved more into the Steve Madden situation and the FBI investigation.
However, they decided to spend the majority of the movie beating you over the head for 3 hrs of repetitive hookers and drug scenes. If the movie was just supposed to be about "what you can do when you make money", then they should have shortened the run time to maybe 1.5 hours.
