There are really great public exhibits that you can see any time. Visit the outdoor sculpture area, the wonderful #D relief of the Grand Canyon hanging over the elevator area, and sometimes the adjacent building has extended free exhibits. The low rating is due to the hit or miss nature of the paid exhibit area. You might get lucky and see classical sculptures from ancient Greece, or you might just see photos from NatGeo contests. That's $15 to walk through an instagram feed in a town where the world's greatest museums are free. In other words, don't go unless the exhibit is something you really want to see, or just pop in to see the free bits when you are in the area.
