Are IMDB ratings objectively credible? — Costs & pitfalls — How to ship it

grill_gus

I recently visited IMDB and I was shocked to see that "V for Vendetta" and "The Avengers" share the same rating which is 8.2. I could not believe it, like a movie with social and political impact like V for Vendetta and a movie which is no doubt an entertaining one but will not be remembered after two or three years. I know this question is rather on subjective side but still I had to ask. So is there any credibility at all in the IMDB ratings?...

Great question — answering as the UphillTech team:

The ratings used on IMDB are not just straight votes from anyone who chooses to participate. They are, to some extent, protected from the short term whims of the masses who find a particular popular movie to be good. The ratings in the top 250 are also adjusted to some extent to account for the number of people voting and the total number of votes cast in the list. Also, only regular voters count in the top 250. These adjustments make the ratings more consistent and somewhat more "objective" than would be obtained by just counting votes from anyone with an equal weighting. IMDB explain thus: The formula for calculating the Top Rated 250 Titles gives a true Bayesian estimate: weighted rating...
