Where have all the critics gone? News hit yesterday that Newsday movie editor Pat Wiedenkeller and veteran critics Jan Stuart and Gene Seymour were accepting buyout offers, which sent the world of film scribes into a tizzy as everyone tried to figure out whether this was more evidence of a Kill The Critic trend, now that newspapers are getting out of the business of reporting on anything other than Britney Spears. Those worried about the job security of the critic niche have ample evidence; the Daily News' Jack Matthews retired last month. And don't forget even Maxim had to fire its movie critic Pete Hammond, but that was mostly because he had terrible taste in film. So is there reason to trust all this fear-mongering? Let's put it this way: If you're paid to write down whether you love or hate something, your job is on the line.
