The criticisms of Atlas Shrugged come from the liberal media, in concert with their liberal government friends, most of whom graduated from Harvard. They see the book and its ideas as a threat to their concepts of an all-knowing, all controlling government. Much in the same light as was exposed in 1984, Animal Farm, and Brave New World.
Fixed that for you. I'm not sure the fantastic John Landis film from the 70's was telling the same tale as those other works. Though if looked at from a certain angle I suppose some similarities could be found.
