I am happy with this app. The only reason it doesn't get a full five stars is that I feel comfortable with my kids being able to browse the tv app I have. It keeps Netflix kids separate and I don't have to worry about their choices as much. If this app did that, I would give it five stars.
My one issue is that sometimes the image is extremely pixelated, but that seems to only happen when the wi-fi signal is very low. Overall the image is crisp and it buffers enough that it doesn't freeze very often.
You do need to have a Netflix account for the app to work. If you think that obvious, well you'd be surprised at some people.
