[Philip Lelyveld comment: the reviewer discusses the multiplex, non-multistory IMAX 3D experience at a theatre in Times Square, NYC.]
[Big Picture Big Sound]
… I should note that my screening of the film took place in an “IMAX 3D” theater. I use quotes because we were in the AMC Empire 25 Cinema in Times Square, which does not use the traditional IMAX film and projectors with their massive 50+ foot high screens. Instead they use DLP digital projectors to capture the “IMAX Experience.” The screen is a bit larger than a standard movie theater, and the seats are closer, the incline greater and the theater smaller so you get a similar screen size effect as in true IMAX theaters. I noticed on several occasions severe cross-talk (doubled lines) as well as collapse of the 3D effect in a few scenes. This is likely a problem with the equipment and calibration more so than the film itself. In any case, I’d say you’d be as well off watching the 2D version as 3D, particularly considering the higher cost of 3D movies.
