I saw it at midnight at the Palisades IMAX and then on saturday on a regular screen.. GO TO THE IMAX!!! It's insane.. the one in palisades is 6 stories high and 75 feet wide.
tried to catch it this weekend in denver at the imax but it was all sold out, and was only in town for the weekend... hopefully ill catch it next weekend when im back home... good to hear the positive reviews
