  We model the consumption life cycle of theater attendance for single movies
by taking into account the size of the targeted group and the effect of social
interactions. We provide an analytical solution of such model, which we
contrast with empirical data from the film industry obtaining good agreement
with the diverse types of behaviors empirically found. The model grants a
quantitative measure of the valorization of this cul- tural good based on the
relative values of the coupling between agents who have watched the movie and
those who have not. This represents a measurement of the observed quality of
the good that is extracted solely from its dynamics, independently of critics
reviews.
