Chicago Sun-Times film critic Roger Ebert has made public a letter he has received from multiple-Oscar-winning film editor Walter Murch in which Murch predicts that moviegoers will reject 3D movies, as they have in the past. (Ebert sums up Murch's comments this way "[3D] doesn't work with our brains and it never will." Murch makes the point that audiences watching 3D films have to deal with what he refers to as the "convergence/focus" issue. "3D films require us to focus at one distance and Converge at another. And 600 million years of Evolution has never presented this problem before" Murch writes. "All Living Things with eyes have always focused and converged at the same point." The problem affects the way Editors do their job, Murch suggests. "The editing of 3D films cannot be as rapid as for 2D films, because of this shifting of convergence it takes a number of milliseconds for the brain/eye to 'get' what the space of each shot is and adjust." In his letter to Ebert, Murch lists a number of other inherent faults with 3D movies, then concludes, "The question is how long will it take people to realize [these faults] and get fed up?"
