Dark Knight in Smithsonian IMAX theater

The Express is recommending that one drive out to Dulles to see the Dark Knight in the Air and Space's Museum's annex's IMAX theater. I've got some friends who did it and thought that it was only so-so because the movie was so dark and focused so much on actor's faces which don't need to be 3 stories tall. Speaking as a museum professional, I'm appalled that the Smithsonian shows stuff like this in what was built to be an educational facility. I guess they've got bills that no honest man can pay. But here's the story if you want to check it out.
