PC Magazine has an article that reviews the various online pay movie services:

But what if you’re in the mood for some longer-format entertainment at a higher image quality, maybe even featuring professional talent? The Internet can help there too.

They vary significantly in what they offer, how you should pay, and whether you subscribe to a film library, rent, or purchase the content. Read on to see which service works best.
