Google announced on the developer blog yesterday that there is a new knowledge graph format, this one for critic reviews. You can see it now, Google says, for movie related searches.
Google will show you critic reviews for movies in the knowledge graph section. Google promises that critic reviews for TV shows and books will be coming this year as well. Here is a picture of what it may look on mobile:
To get this working for your critic review web site, you need to add the critic reviews structured data.
