In many ways movies are closer to architecture than novels because there are far more constraints on the artist. Conceder how a useful hospital and a successful blockbuster are both built for the masses, yet using what freedom remains and artist can still create art and not just another forgettable commercial success.
That's another axiom with which I suspect White would disagree. I don't think White considers a film a success just because the filmmaker accomplished what he/she set out to do. White indeed treats film criticism like literary or other art criticism--you identify a set of criteria, perhaps arbitrarily though ideally derived from the history and cultural context of the medium, and criticize a film against those criteria.
