Netflix is very active in their development and improvement of their infrastructure and is fairly transparent about their strategic technology choices.
But one complaint we've had for a couple years has seemed to fall on deaf ears.
We stream Netflix movies from our PlayStation 3 and from our laptops for our kids almost every day. My wife and I frequently watch Netflix movies and TV episodes a couple of times a week. Most of the time, we have our Netflix parental control settings set to "Unrated Family and below" to keep our kids from watching anything that isn't kid-friendly. Whenever the grown-ups want to watch a movie that isn't allowed on this current setting, we have to navigate to our account settings and change it to a higher rating setting, and then change it back to "Unrated Family and below" when we're done. Yes, this is a minor inconvenience, but I'm willing to do it to keep our kids safe. The only problem with this scenario is that it can take up to 8 hours for the parental control settings to hit the PS3. So if my wife and I want to watch a documentary that is not rated, we must change the parental control settings to "All Movies," and remember to change it back to "Unrated Family and below" when we're finished. If we forget to change the setting back, our kids could see all sorts of unsavory movie covers that can be pretty inappropriate, especially for little children.
We have called and explained to Netflix customer service representatives several times over the last couple of years that we would love to see this feature, and they very kindly have told us that they will submit it as a feature request. When I recently asked about this feature, I was told that a majority of Netflix customers must also request this feature before Netflix will consider implementing it (which makes sense from a business standpoint). Technically, I suppose that I could accomplish my objective by paying for a second Netflix subscription (one for me and my wife, and one for the kids), but I shouldn't have to subscribe twice.
Aside from protecting children from seeing non-kid-friendly movies (even many movie cover photos can be pretty inappropriate), this seems like an intuitive feature change that would benefit all Netflix subscribers with different household queues and recommendations. Does one Netflix Watch Instantly queue fit your family's needs? Until enough customers complain about it, apparently Netflix isn't very motivated to make this much needed change.
