The opposite effect, a bad movie being rated highly, also occurs. One example of this is with the film "The Oogieloves in the Big Balloon Adventure" (http://www.imdb.com/title/tt1520498 http://www.imdb.com/title/tt1520498). This film was panned by critics on release and was a complete flop at the box office. Its IMDB rating languished until sometime last year when it began to rise. Around the same time, a bunch of poorly-worded unequivocally positive reviews showed up on the page, all following the same pattern (including one that appears to have been run through a translator and back). The rating made it up to 8.0, although it's since fallen to 7.6. If it's not the movie's production or marketing team involved in this clear manipulation, I don't know who it would be, as I can't see that this movie has any kind of cult following.
