I was promised 3-D

We went to see Harry Potter at the IMAX yesterday. That meant going to Chantilly, VA, which is really far away. And, as it turns out, amazingly sketchy - that not being the point. The battle at the Ministry was supposed to be in 3-D. But the screen at the Air & Space Museum Udvar-Hazy Center (or the "auxilliary location" as most people consider it) doesn't have a realy IMAX screen. It's just really big. But it isn't the kind that starts wrapping aroung the walls, which is what allows them to project in 3-D. So it was really big, but the picture was still flat. For all the time it took to get out past Dulles airport, I was expecting more, and I am quite upset about it. Damn you, Smithsonian Institution.
