I am of a mixed feeling about Netflix, personally. I do enjoy the streaming but their library of movies for that medium is limited. Many of their videos are DVD/BRD only, which is why I keep that service. Now, back in the day, I was paying for delivery and the streaming was free. But, since they instituted separate costs for both services, I feel I'm being double-tap charged and penalized for their lack of product on the streaming end. I am, however, extremely glad that they didn't go through with splitting up the two services into two separate companies with two separate accounts, bills, etc. That would likely have been enough for me to ditch the whole thing. I just hope that, one day, their entire inventory will be available for streaming so I can turn off the deliveries for good.
Instant Streaming is great for TV shows, but yeah, their movie selection is still somewhat limited. Luckily, I don't really watch movies anyway, so Netflix is perfect for me. Any movie I really want to see I have either a) already seen in the theater or b) purchased on Blu-Ray.
