Box Office Power Rankings: Charting the Dumping Ground Print

chart-small.jpg Quarantine won this week’s Box Office Power Rankings, and my first thought was that, with Rotten Tomatoes and Metacritic scores of 61 and 54, respectively, the horror flick would have done even better a few weeks ago. Sure enough, those scores would have secured an additional five points for Quarantine

because of weaker competition.

That got me thinking about dumping grounds — the conventional wisdom that early in the year and after the summer movie season, Hollywood drops its unwanted product on the market just to be rid of it. I decided to try to quantify the dumping ground.

I combined the median and average Rotten Tomatoes and Metacritic scores for each weekend’s box-office top 10 through July 20, 2007. Because both measures use a 100-point scale, one would expect that a typical week would have an aggregate score near 200 — or 50 each for median and average on Rotten Tomatoes and Metacritic.

The accompanying chart shows that — at least over the past 15 months — the conventional wisdom holds true. The obvious valleys fall in early autumn (post-blockbusters) and late winter (post-awards bait). The noticeable peaks are in late summer and the holiday season.

The highest aggregate score recorded so far was 267.4 for the weekend beginning July 20, 2007, with six movies scoring 76 or higher on Rotten Tomatoes, led by Ratatouille, Knocked Up, and Hairspray. The nadir of 145.9 came the weekend of March 7, 2008, with six movies scoring 27 or lower on Rotten Tomatoes, including 10,000 B.C., Fool’s Gold, College Road Trip, and Jumper.

About Box Office Power Rankings

Box Office Power Rankings balance box office and critical reception to create a better measure of a movie's overall performance against its peers than gross receipts alone.

The weekly rankings cover the 10 top-grossing movies in the United States for the previous weekend. I assign equal weight to box office and critical opinion, with each having two components. The measures are: box-office gross, per-theatre average, Rotten Tomatoes (RottenTomatoes.com) score, and Metacritic (Metacritic.com) score.

Why those four? Box-office gross basically measures the number of people who saw a movie in a given weekend. Per-theatre average corrects for blockbuster-wannabes that flood the market with prints, and gives limited-release movies a fighting chance. Rotten Tomatoes measures critical opinion in a binary way. And Metacritic gives a better sense of critics' enthusiasm (or bile) for a movie.

For each of the four measures, the movies are ranked and assigned points (10 for the best performer, one for the worst). Finally, those points are added up, with a maximum score of 40 and a minimum score of four.
