I don't know about you, but I abuse Netflix. If I don't like a movie I'm watching, I stop it and I don't get charged extra. Plus, unlike REd Box, you can preview a movie before you decide to watch it. For newer movies that I'm interested in, I prefer to buy the Blue Ray verision. There are movies I never tire of watching plus I don't have to return them. I also have a large collection of DVD's. The eight dollar charge for Netflix, is minimal for the movies I do watch. It sure beats the expensive premium channels that show movies I don't care for, not to mention,that you have to watch them on their schedule.
Netflix is a waste of money. Red Box is the way to go if you want to watch anything that was released this decade.
Either way, it's a matter of preference.
