The Wolf of Wall Street

Piece of shit movie. It just told me that America is a lousy country "full of self-serving, shameless, morally bankrupt, soul-less people"...too.
When watched it at home, I didn't mind to mop floor, take a leak, dig information about some pretty faces in this movie, fetch some snacks, polish my finger nails, talk on the phone with my girlfriend about shopping thing...anything, but that was really the whole thing I did when watching it. It was a long long long three hours anyway.
So why it is going to win an oscar? Or just because I am a non-US and don't know how to view this movie?
