Block Buster charged me almost seven dollars for a movie once. I never went back. I like to choose a movie online to pay for on a one on one basis. I pretty much went through all of Netflix’s movies I wanted to see so I couldn’t see paying the monthly fee.
You might want to try out iTunes. They charge by show/episode.
I did that route with the first season of Primeval, but at a $1.99 it can start adding up pretty quickly.
