The Kimball is in an excellent location and what it offers - for free - is an excellent value. That said, the quality of their offerings varies widely and many of their exhibits, while interesting, are hardly spectacular. Individual artists are given space and promotion, but some are less worthy. The current stuff is a perfect example. The Lego art display is quite interesting and a delight for children, but to be honest it doesn't pass the interesting stage. The artist is good but not great. The other two exhibits are much lower on the scale. The 'line art' was so imaginary it is a wonder it passes at art at all. Different strokes for different folks, but everyone I saw in the basement had a What? expression. Then there was the playing card size house paintings in the canteen. Hmmmmmmm.
