As I've written before, Netflix streaming is not a particularly good deal if you want to actually watch movies that people want to watch. With the end of 2014, the streaming catalog is about to shrink yet again:
For a while, it was also possible to find out what was expiring, information that was valuable to the Netflix user who maybe wanted to watch something before it disappeared from his or her Instant Queue (which is now called "My List"). Earlier this year, Netflix removed the ability to easily find out in bulk what titles were expiring from its library, which means that users on Reddit and other sites have picked up the slack.

The page has a list of movies going bye-bye. It includes Being John Malkovich, Eternal Sunshine of the Spotless Mind, Titanic, Serpico, and Capote. Stop and think whether you would consider a movie service good that lacked these movies.
It's telling that Netflix is actually removing the ability to easily see what is disappearing from its service. My sense of it based on earlier surveys is that less than a tenth of movies available on DVD are streaming on Netflix, including popular blockbusters. The company has every reason to hide it.
