I have had Netflix since the end of 2000. Although there have been periods of a few weeks where sending or receiving was buggered by our friends at the post office overall it has been a goddamned cinematic blessing.
I hate going to the movies but with 70 movies in my queue and two out at a time I'm kept busy. Plus they have lots of obscure stuff, foreign movies, and unrated flicks. It is rare that I want something that's available on DVD but Netflix doesn't have it.
So that's a strong thumbs up for Netflix.
