The always-improving Netflix Web site has new features!
Have you noticed the movie descriptions that popup when you put your mouse pointer on a title? Well, now you can turn them off, if you want. It's under Account Details in Your Account. Click on or off the box next to "Enable extra movie information".
In addition to rating movies, you can also rate genres. This way, Netflix won't bother to offer recommendations to you in genres you don't like.
