Reviewers score the pacing 46/100 in their films, across 21 reviewed titles; fans 55, detractors 29. The element that speaks to their work as an editor.
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.
Is Mark Day's work okay for kids?
Across up to 16 MovieCove titles with content scores, sex & nudity runs lighter than most films.
Severity 0–100 from the Content Guide. Categories with under 10 votes on a title are not counted. The band's colour is the severity of their median, named beside it.
