As I’ve done in past years, I’ve taken the feature films that IMDb counts as 2013 releases and multiplied their IMDb Bayesian average rating times their Rotten Tomatoes critic percentages. Excluded were films with fewer than 2000 ratings, films with fewer than 20 critic reviews, and all documentaries. And so here are the top ~30 films—all that scored over 6.0:
