While you will have to pay for movies on Vudu, you don't have to sit through a mire of commercials, and advertisements. Not to mention, the mechanics of the site are a hell of a lot better than Crackle's. And, as of this year, Vudu has started streaming movies for free. And while their selection may not be great, like I said before, you don't have to sit through a mire of commercials, and advertisements.
