I use a couple of movie review sites to get a flavour for a particular film, and I’m starting to think they are actually quite pointless.
Most of them allow you to rate a film out of 5 or 10 stars - or even using a percentage. Very useful you might think, until you realise that the sheer volume of people using them (1000s) mean that they are pretty much useless.
For example, I just looked through 100 film recommendations on Love Film.com, and almost every single one of them had three stars. On other sites, I’ve noticed that movies tend towards exactly that - around 60%. Why? You can’t give no stars in a rating, so the median rating will always be 3 - and over such a huge number of people, the mean will tend towards that number too.
The best site I’ve found is Rotten Tomatoes, which collates critics, who are usually a bit more discerning. The scores there do differ much more. But even there, you still get wildly different reviews.
All of which tells me, you can’t tell how good a film is going to be unless you’ve seen it. How profound.
