A handful of movies have locked down that elusive 100% rating on the uber-popular review site Rotten Tomatoes. It’s a tough task, one highlighted by the humongous movies that don’t have a 100% next to their names, including The Godfather, Saving Private Ryan, and Daddy’s Home 2. So when we tell you a new movie has taken the crown for best score in Rotten Tomatoes history, you may want to put it on your “To Watch” list. Lady Bird, a coming-of-age movie from Greta Gerwig, has a perfect 100% through 170 ratings. That beats out Toy Story 2, which had a perfect 100% through 163 ratings. Basically what that means is, 170 critics say Lady Bird and every single one of them gave it a thumbs up. Not bad. Check out the trailer and go buy some tickets.
