Flickchart

Which movie do you prefer, "Casablanca" or "Fast Times At Ridgemont High"? What about "Ghostbusters" and "Beverly Hills Cop"? "The Godfather" or "Gandhi"?

If you like movies ... I mean really like movies ... set up a Flickchart account. By choosing your favorite of hundreds of pairings of movies, you gradually develop a list of all the movies you've ever seen, ranked in your preference order. It takes awhile for your list to seem valid, because it takes literally thousands of head-to-head votes to develop a mathematically significant list. But after an afternoon or three of ranking, you'll be amazed at how accurate your list can get.
