Hubble 3D
This was no more than a short documentary about the Hubble missions and some of the things that the telescope had revealed, but it was my first 3D and my first IMAX in over a decade (perhaps two), and I was blown away by the experience. The nebulae and flying-through-space scenes were amazing, and really drove home the vastness of space. The next nearest galaxy, Andromeda is 2.5m light years away, and our local cluster is just a "village" with a few dozen galaxies compared to a "metropolis" of many thousands!
It makes me want to go to a planetarium again...
