Go watch Boiler Room instead, or at least also

Rating: 4/10 (4 February 2014)

Wolf is entertaining enough, and Leonardo does another bang-up job, but the movie is also a good example of Hollywood turning out a movie that technically shows the hazards of excess but in the process revels in the excess to such a degree that you have to push aside the 95% of the film that revels in sex, drugs and greed to notice that, oh, yeah, lives are wrecked in the process. If you didn't come out of this thinking that some drugs and some gang sex are the next thing to try, then you are a thinking person and a conscious, active viewer. Congratulations.
I would say instead of seeing this, see Boiler Room and watch Giovanni Ribisi, Vin Diesel, Nia Long, Nicky Katt, Scott Caan, Ben Affleck, and Jim Young perform Writer/Director Ben Younger's far better movie. To be fair, Wolf contains several admirable performances, but that doesn't make up for the self-indulgent movie they wound up in.
Boiler Room actually contains a few characters you might care for. (I didn't really care much what happened to anyone in Wolf, except the victims, who are entirely off-screen.) It is a tighter film by far, indicating excesses without offering them up as the main dish. Tightly written, well acted, simple and honest.
If you will only see one of these two, see Boiler Room. If you must see both, see Boiler Room first so that you can see how Wolf pales by comparison as you watch it.
