This was the second time we saw the movie and we wanted to experience it in IMAX. The screen size and sound were the most obvious improvements. Picked up lots of things the second time that we missed. We love all things Star Trek and the new movie was awsome. My sister and brother in laws that aren't into Star Trek even liked it. Very entertaining in IMAX. I'd suggest IMAX for any BIG effects movie. So what if you can't talk during the movie! We're looking forward to Transformers.
