Hoisting movie ratings

You've written a script to scrape data on your favorite movies from the Open Movie DataBase API. Now you want to process the JSON data to extract the Rotten Tomatoes rating for each movie. You've been given a data frame named movie_df which holds the JSON responses for five movies. You'll explore this data with unnest_wider() and unnest_longer() before switching to hoist().

The dplyr package has been pre-loaded for you.
