Yes, you can watch Netflix with someone on FaceTime. You can either use the built-in FaceTime app on your iPhone or iPad, or you can use a third-party app like Skype or Google Hangouts. To watch Netflix with someone on FaceTime, you'll need to have an active Netflix subscription and the other person will need to have an active FaceTime account. Once you have both of those things, you can start a FaceTime call and then use the Netflix app to stream a movie or TV show. The other person will be able to see and hear the movie or TV show that you're watching, and you'll be able to chat with them at the same time.
