I really like the hobby(?) project <a href="http:&#x2F;&#x2F;www.phi-phenomenon.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.phi-phenomenon.org&#x2F;</a> which attempts to create a definitive weighted-aggregate of movie rankings using:<p><pre><code>  many different types of lists to measure film quality
  ... polls of the general public, of academics, of critics,
  and of filmmakers.  Some of these polls ask respondents to
  list their favorite films. Others ask respondents to rate a
  large number of films. There are single author lists by
  critics, academics, and filmmakers. There are lists that
  focus on how films are rated by video guides or on how many
  awards the films received. Some lists try to call attention
  to obscure films. Others stick to the obvious choices. Some
  attempt to measure film quality directly. Others include
  factors such as the historical importance of the film.
  
  The use of different types of lists and the statistical
  methods used help to minimize the effect of factors other
  than quality in order to create a purer measure of a film&#x27;s
  greatness.

  It is not perfect, but it is closer to perfect than any
  other method is.</code></pre>
