Shooting wide open, blurred backgrounds with main subjects often out of focus, etc., has long encroached beyond the realm of still photography, at least here in Germany.

As a DOP myself, I sometimes have discussions with directors about that "look" that has become so trendy amongst the younger generation of camera persons with gadgets like the 5d with fast lenses, who say things to me like "it does not matter if even the main subject is sometimes out of focus, it adds to the aesthetics of THAT look"!!

Of course it looks different, I can even understand the allure of Bokeh, but there has to be a balance between "look" and content. It has to make sense.
