How to rate movies on AppleTV I just rented a movie on Apple TV.  How do I give it a star rating, i.e 1-5 stars? 

When you select a movie on Apple TV, it shows a rotten tomatoes rating and a star rating. In the past I stumbled across the star rating selector UI by accident- now I can't find it. 

I have a third-gen Apple TV running 6.0.2.
Currently (March 2017) you have to login to iTunes to rate and leave a review. I hope they add this feature to Apple TV soon.
