Why do updates to data or votes for smaller films take weeks while information and user comments for big films are added almost overnight?
Updates are performed at regularly scheduled intervals, regardless of a
film's size or release schedule. Data sections (i.e. information like the cast/crew of a
film) are updated on a weekly basis, while user votes are
recalculated on a daily schedule.
Moreover, user ratings do not appear until
a minimum amount of votes from those who have viewed the film have been collected. For obvious reasons, this
threshold is reached more quickly with popular films than on less
widely-released features.
