The Story Behind the Worst Movie on IMDb
538 is using the wrong metrics.  For a movie to be truly, truly, <i>sublimely</i> bad, that badness needs to be recognized - people in some cases will want to watch it for its incredible badness.  This means that there are going to be a disproportionate number of both 1 and 10 votes.  And the winner based on this is - The Room. <a href="http://www.imdb.com/title/tt0368226/ratings?ref_=tt_ov_rt" rel="nofollow">http://www.imdb.com/title/tt0368226/ratings?ref_=tt_ov_rt</a>
