Let us (users) like or dislike / rate a movie on Bing website.
Let us (users) like or dislike a movie on Bing website. For example someone searches for a movie on Bing, say La La Land, let users rate / like or dislike the movie. That way you will have your own data, you don't have to depend on IMDb or Rotten Tomatoes for movie ratings, or you can display Bing movie ratings right alongside IMDb rating. You can use that data for Cortana recommendations as well. Google has that feature now.
