I did the exact opposite, and canceled OR rather declined the unlimited streaming option. Now I only have DVDs by mail, which is perfectly fine to me.
As it stands, there really is absolutely nothing of value for me or my family on Netflix's streaming service. About the only use we got out of it, was streaming some children cartoons. However, I also have Video on Demand from my cable provider so I can live without streaming Netflix.
Until Netflix's streaming library equals their DVD library in size, then I am not paying for it.
I am also not going to pay for them to slowly build the library to a size that I deem worthy, as I am obviously not getting my value during this "building process".
I however will go back to their streaming service once the value equals the quality, but not anytime sooner!!!
