I use Netflix for streaming mostly movies, documentrys, and TV series. I get the Netflix DVDs also. I cut the cable bit about 6 years ago and have OTA TV in HD and get about 45 channels where I live. The only bad part is the cost of my DSL from Comcast which is 39.95 now but going up to 64.00 in about 10 months. I get 25-30 MPS and am wired in, so I don't get buffering. I used to have AT & T but they kept climbing in price and the download speed was only 2.5 MPS. I only had buffering once in a while. I don't mind the picture quality on Netflix, and consider that half the time the movies and the time they were made, or by whom has a lot to do with the quality. Sure Blu-Ray DVDs are better though. I watch a lot of 3D movies on my projector, that I buy used. It's all a way lot better than we had 20 years ago.
