Go to your netflix account and log in. When you get to your account it will look like this clcik on "YourAccount and Help" :
When you do that it will bring you here. Scroll down to Preferences. Click on the Change Parental Setting:
Before you get to this screen it will ask you to log in again. Then it will show this. Pick your rating and save.
Now, I picked PG13 and below because Lee and I love action movies like Bourne Identity and other figure it out movies. So we chose PG-13 for a little action but not violence BUT i realize that there are tons of PG-13 movies out there that can be "shady" and the netflix customer service guy said that there was one more thing I could do to make sure PG-13 was a movie that was appropriate.
Click on the Tab Movies You'll Love and then click on Taste Preferences
Here you can choose what movie not to suggest. These wont be blocked (unless their rating is one that you blocked by the parental control) but they just won't suggest them to you and you won't see them while you are scrolling to watch your Disney movie. You can choose Never, Often, Sometimes. You can see what I picked below. I said never to "Steamy", "Raunchy", "Controversial" and much more....
