IMAX's Time Square trip

I Heard the trip to IMAX's cinema Time Square, KL. The purpose? I think is was to study the huge IMAX's screen which are curvy compare to other cinemas which has flat screen. Though when the movie starts playing, the image are just in normal size as other cinemas due to the IMAX's cinema lack on budget to bought an IMAX's film which disappoints me a little. But, discovering the curvy IMAX's screen was rather interesting. Our lecturer asked us which are the best spot to watch the movie. I figured it was suppose on the middle, straight to the middle of the screen but I was wrong. At the end of the movie, he told us, the best spot is not actually viewing straight to the middle of the screen but from the sides. This is because, when you viewing from the middle and straight to the screen, your eyes can't read the the images on your left and right due to the curve of IMAX's screen.
