It sure isn't Goodfellas, but it isn't as bad as some reviews seem.

Rating: 8/10 (1 January 2014)

Full disclosure off the bat here: I've owned the book written by the gentleman (Jordan Belfort) that this movie portrays for years, and thoroughly enjoyed it. Most reviews I see that have a strong negative impression seem to be misguided at best, as FIVE seconds of research into the book or character could have alerted anyone as to the content of this movie.
Now, as far as dark humor goes I am a big fan, and Scorsese's venture into this arena is certainly successful. Leo gives the performance of a lifetime, and Jonah Hill manages to pull off a role that I thought he was terribly miscast in. Should you expect this movie to be relevant to finance, you'll be disappointed. However, it was listed as a comedy for a reason. I work in the industry and had no qualms with this film.
The supporting actors did fantastic jobs for the relatively short scenes they were allowed. Matthew McConaughey, Jon Favreau, and Rob Reiner all did a fantastic job with what they were handed, contributing to some laugh out loud moments. This is NOT to say that the movie is without flaws, however. This 179 minute picture could be 30 minutes shorter, and even for a single 20-something male the amount of nudity was not really needed. I have no problem with the concept of attractive women, but if the scene is boring or serves no purpose then stick to the original 6 sex scenes. Additionally, the conclusion of the movie seemed to appear from nowhere, without significant drama or build-up. However, this being a comedy, I don't expect much else.
All things said, the movie is humorous, laugh out loud funny at points, and draws a little bit of satire out of the script as well. Great watch, and another good performance from the Scorsese/DiCaprio duo.
