Movie review aggregating website Rotten Tomatoes has added a section for "verified" ratings, where it will display ratings from moviegoers who have bought tickets via Fandango.
Before, anyone could rate a movie on Rotten Tomatoes whether or not they'd seen it, so those dissastisfied with the casting, concept or promotion of a film could easily give a film a low rating that didn't reflect its quality. For example, Captain Marvel was deluged with bad reviews before it even opened in theaters.
Now, trolls and other bad actors can still rate movies poorly, but there is a separate score from people who have definitively seen the movie in question (see graphic above), giving the score more credibility.
AMC, Regal and Cinemark plan to join Fandango as authenticators later this year.
