Over the weekend I saw Harry Potter and the Half-Blood Prince. Actually, I had seen it two weeks ago. I went to see it again this last weekend, not because I'm a Pottermaniac, but because I wanted to see it in a different theater. Because of the limitations of theaters, when this movie first came out, I was only able to see it on a regular screen in 2-D. For my second viewing I saw it on an enormous IMAX screen. Not only is it bigger than regular screens, but the film travels through the projector much faster than for regular films, giving it a more realistic feeling. AND...it was in 3-D, really drawing you into it. There were many gasps in the audience as things seemed to fly right
