Its such a close up, virtual experience in a real 3D IMAX theatre that you feel like you're tumbling through space. Your pulse will rise, you'll probably scream o-sh*t as debris flies right at you in space... I ended up a bit nauseous with all the spinning.

Watch the trailer and you'll see what I mean. Make sure its not 2D, IMAX, RealD - to get the full experience, go for the IMAX 3D. It's a $6-8 rough surcharge on top of a normal ticket.
