Because of Phillip Seymour Hoffman's death I remembered this movie he was in, "Happiness" by Todd Solondz.

It's a very dark satire of modern life, it shows the lives of different people which live "normal" lives while strongly showing the dysfunction underneath. It's pretty hard to describe because Todd Solondz's films are their own genre, they feel like a strong punch in the gut. A "feel-bad" movie is probably the most accurate genre for it.
I know the movie industry rarely spits out a work that doesn't enforce the viewer's prejudices, and Happiness is one of those movies. The movie itself from what I know was distributed very poorly, they even tried to sugar coat it. Check this trailer out which makes it look like a comedy:
