For the last 15 years or so, I’ve been using IMDb to look up how good movies are supposed to be. I also try to do my bit by submitting ratings for those I’ve watched. So far, I’ve rated nearly 700 films. In recent years, I’ve noticed more and more people referring to Rotten Tomatoes as their trusted source. Also, IMDb has started listing Metacritic’s score alongside their own, and Google can show all three in their search results for a film. Naturally, I had to go and look at the data to figure out which site I should be using.
