The "Hollywood machine" would not exist if a large proportion of the public did not want to see the movies it produces.
There is a place for the "Hollywood machine," just as there is also a place for pretentious art-house crap and Dogma-95 and all the rest of it. Hollywood would be no more palatable if it was all like Von Trier and his ilk, vs. how it is now.
Side note: I suppose this increases the likelihood that Transformers 4
will be a remake of the 80's film...
