Percentiles are each film's standing among all films on MovieCove; the typical film is the median, so one outlier cannot drag it. Percentiles and reviewer scores count the films IMDb credits them on, for now; the Midcredits score bands, the shape of the crowd and the two cards count their MovieCove titles, shows included (a show ranked among shows), appearances as themselves left out. A descriptor is the shape of a title's IMDb rating distribution against the catalog; "most divisive" needs a spread wider than half of all titles, and a card names only a principal credit: a craft role, and on a show a crew role or a run of episodes, never a courtesy credit or a one-off guest spot.
