Oh I went to this exhibit also.
It was actually quite entertaining to see. Took all sorts of pics too. I thought most of the costumes looked great and were very nicely displayed, but I did have two gripes about the visit. First, I would've wished to see a lot more kinds of OT costumes upstairs. Second, did anyone else notice how lazy the display was for the OT Stormtrooper? I'm sure the details were literally colored on by a marker, and velco could be spotted in several areas (didn't even have to look closely to spot either of these).
Overall, though, it was worth a look and something nerdy to do as an extended Valentine's Day gift this year :)
