Statistical Patterns in Movie Rating Behavior.

Ramos M, Calvão AM, Anteneodo C - PLoS ONE (2015)

Bottom Line: We find that the distribution of votes presents scale-free behavior over several orders of magnitude, with an exponent very close to 3/2, with exponential cutoff.It is remarkable that this pattern emerges independently of movie attributes such as average rating, age and genre, with the exception of a few genres and of high-budget films.These results point to a very general underlying mechanism for the propagation of adoption across potential audiences that is independent of the intrinsic features of a movie and that can be understood through a simple spreading model with mean-field avalanche dynamics.

ABSTRACT
Currently, users and consumers can review and rate products through online services, which provide huge databases that can be used to explore people's preferences and unveil behavioral patterns. In this work, we investigate patterns in movie ratings, considering IMDb (the Internet Movie Database), a highly visited site worldwide, as a source. We find that the distribution of votes presents scale-free behavior over several orders of magnitude, with an exponent very close to 3/2, with exponential cutoff. It is remarkable that this pattern emerges independently of movie attributes such as average rating, age and genre, with the exception of a few genres and of high-budget films. These results point to a very general underlying mechanism for the propagation of adoption across potential audiences that is independent of the intrinsic features of a movie and that can be understood through a simple spreading model with mean-field avalanche dynamics.

Color map of the number of votes ni vs. the budget bi of each IMDb movie i.Each bullet contains the number of movies indicated by the color scale. The vertical lines indicate the quartiles. The dashed line was obtained by means of a non-parametric regression rLOESS [15].

pone.0136083.g008: Color map of the number of votes ni vs. the budget bi of each IMDb movie i.Each bullet contains the number of movies indicated by the color scale. The vertical lines indicate the quartiles. The dashed line was obtained by means of a non-parametric regression rLOESS [15].

Mentions: Last but not least, we investigated the dependency between the number of votes and the production budget bi of each movie. Information about budgets is available for a reduced set of feature films, and we considered those with a budget above 103 US$ (approximately 18 thousand films). For this set, we plotted the number of votes vs. budget (Fig 8). This plot shows that points are scattered but display a positive correlation beyond the first quartile, indicating that above a tipping point, on average, the number of votes increases with the budget, although there exist high-budget films with low appeal and low-budget ones with a moderate response.
