6. A 5 Star Product

So how many movies do you see or cd's do you buy, based on the number of stars out of 5 that the mass media give to everything? I know I do. A 4 or 5 out of 5 given to a movie or CD in Time Out, Guardian or even Q indicates one I will consider investing in.

But isn't criticism subjective? The media seem to think there are various levels of subjectivity though and giving marks out of 5 is a simple indication of how good a CD or movie is.

So why aren't there stars out of 5 given at the end of theatre or book reviews. Why is it considered easier or more appropriate to give marks to an art form of a piece of music or film but not to a book or play?

answers on a postcard please.....?
