No, I don't watch enough movies to make Netflix worth my while. Besides, I can get them for free from my library, though I have to wait for the newer, more popular ones. I'm #68 in line for Slumdog Millionaire.
I do watch both movies and TV shows online (for free), but it's much nicer to watch them on my TV. Also, for some reason the DVD player built into my TV works without overheating, while every computer DVD drive I've had has overheated after so many hours of play.
