It's 2013. I can stream whatever movie I want right now from Netflix or Hulu.
Are there exclusives or something?
Yes. As Daemon mentioned, HBO is better (or at least as well) known for its original programming. To mention just a few that are current:
Game of Thrones
Boardwalk Empire
True Blood
Girls(I watch the first three)
As for past series, there have been a couple of gems that you might have heard of, such as
The Sopranos. There are also some excellent documentaries, such as the currently running
Mea Maxima Culpa, about the first-known public protest against clerical sexual abuse.
