Yep, Hollywood is increasingly cutting critics off from advanced screenings of movies. Such is the case with Iron Man, much-anticipated among those of us who love Stan Lee’s Tony Stark. Critics have been told all over the country that there will be no pre-screenings of the movie (you can guess with some measure of confidence that this does not apply to the biggest of media outlets). It’s the new reality of movie criticism and maybe it’s not such a bad thing. All the advance hype and hoopla long ago got out of hand thanks to the Guy with the Big Thumbs. And maybe this new reality suggests something else, something that has thus far escaped observers who have been busy commenting the stark new realities of movie criticism: If critics have, as many have said, lost their credibility, why is Hollywood cutting them off?
