Are even turkeys made with loving care?

Watching the "making of" documentary that comes with "The Social Network" I came to the conclusion that these films are mainly done to gratify the egos of the film's makers by underlining just how seriously they take their work. From the scenes where David Fincher, Aaron Sorkin and the two lead actors sit in a conference room and weigh every word of the dialogue (most of which is going to go right over the audience's heads) through the ninety-nine takes of the opening scene in the bar to a Winklevoss twin confiding that somebody had pinned his character's notional Harvard timetable next to his desk, it was a portrait of almost demented fastidiousness. This being "The Social Network", it's all seen as worthwhile, but people must presumably be going to the same trouble on films that are going to open on Friday and then close a day later.
