The Dangers of Crowdsourced Ratings

This is an interesting article about how IMDB’s ratings system was gamed.

The Story Behind the Worst Movie on IMDB

If you try to find the worst movie on IMDB by fan ratings, it’s not Battlefield Earth, Troll 2, Ishtar, Gigli, or The Hottie and the Nottie.

Instead, it’s the Bollywood movie Gunday, which got reasonable reviews from critics.

The issue is that the film makes reference to some events in South Asian history which offended a lot of Bangladeshis.

This led several activist groups to start a social media campaign encouraging people to give it a 1 star rating on IMDB.  About 40,000 people did so, completely overwhelming the approximately 4,000 people who rated the movie based on their genuine opinion of its quality.

Just something to keep in mind when looking at IMDB or Rotten Tomatoes’ ratings.
