Western Vs World
The phrase 'world cinema' is generally used to describe 'foreign' films and 'foreign' language films. The world cinema section in the likes of HMV usually has non-english speaking films. I would refer to 'western' cinema as US/British I suppose.
These days I find that world cinema tends to hold some sort of artistic value that US/studio films do not. The studios churn out blockbusters all the time and, with the exception of a slim few, I tend to watch and forget.
Not wanting to generalise US films or British films. We have produced some greats, however in my opinion they generally come from the indie film makers.
When i watch a film I like to be intellectually and emotionally stimulated whether it is a 'western' film or 'world cinema' flick, and i think that the appeal of world cinema is that they seem less about the money and commercialism and more about making awesome films.
