As a satirist of popular culture, Mike Judge is comparable to Stan Freberg. (I know -- no one reading this knows who Stan Freberg is. Look him up.) "Beavis and Butt-Head" is a remarkable documentation of the irreversible decline of American society, and "Office Space" and "Idiocracy" are classics of social criticism. (I can't think of a less-pretentious term.) "King of the Hill" isn't quite so good, but I ascribe that to Fox's insistence there be no extended story arcs.
"Extract" is a disaster. It's a 60-minute idea padded to 90 minutes with over-written dialog. (It takes an hour to get to the point it should have reached at 30 minutes.) Worse, there's no obvious dramatic or comic "point" to the story to drive it. Judge's direction is uncharacteristically sloppy and unfocused. And unbelievably, Judge has had David Koechner (whom you probably know better as T-Bones) duplicate Gary Cole's delivery in "Office Space".
These things might not have been as important if the film were funny. It isn't. It has one or two funny lines, and that's it.
A good script reader would have caught most of the story's problems -- in particular, that there really is no story there -- but I suspect Mr Judge has reached that point of success where you no longer have friends who will tell you the truth.
If you insist on seeing "Extract", rent it, don't buy it.
