* Have you watched the tv show "Friends"? Why do so many people like it? It shows us life in America, is that the main reason? (or 'It tells us about the lives of Americans, is that the main reason?')
It may be that Friends is very popular abroad because it shows an idealized version of the lives of people in their 20's in New York City. And it is funny and has characters of both gender. But it is not really an accurate portrayal of life in America.
