Black Panther has already achieved several impressive feats, but there's no way many expected it to become the #1 movie of all time.
That is the case though according to Rotten Tomatoes, at least at the moment. Black Panther currently holds the #1 spot on the top 100 movies of all time list, but it also holds the #1 spot in the top 100 action & adventuremovies list.
