Plus all the big national papers: the Times, Post, Journal, and LA Times, plus all the trades: Variety, Hollywood Reporter, Entertainment Weekly all shat on it, and many of the small local paper reviews that are counted as positive are mixed at best:
"Although never boring and almost continually amusing, Extract doesn't work as a movie because you don't buy a minute of it, even as silly satire."
or
"Extract has some flavor, but the comedic kick is diluted by flat characters and a thin story."

It reminds me of something Tim Heidecker said about the horrible reviews for 'Tim and Eric's Billion Dollar Movie': "If you're a critic and you walk out of a theater wondering what the filmmakers could have possibly been thinking, maybe you missed something?"
You would think critics would give the benefit of the doubt to the guy who made Idiocracy and Office Space, especially considering the critical reappraisal each of them has gotten in the years since their release.
