I saw this exhibit when it was here in Los Angeles a few years ago. Definitely worth seeing if you're a Star Wars fan.
We went during the week, thinking it wouldn't be too crowded. Boy, were we wrong! There were three or four large groups of small children that had been brought to the exhibit on a school field trip, and their adult chaperones were not up to the task of wrangling those little monsters, so it made getting decent photos of any of the exhibits nearly impossible. :angry
