This movie came up in my Netflix queue this week and, despite the dour subject matter, it's one of the best films I've seen this year.
As a related, but obscure, note, the number one method of suicide in the United States, by a fantastic margin, is the use of a firearm; self-inflicted gunshot wounds account for 52% of deaths. The next highest (hanging) accounts for a much smaller 22%, while wrist-cutting (despite its cinematic prevalence) is a paltry 1.5%. In Europe, interestingly, firearms and hanging switch places but otherwise keep roughly the same percentages.
