A short review of the exhibition was on the Social Affairs Unit blog. The strap is "A minister's egg of an exhibition but parts of it are excellent".

I had to look that phrase up and discover that it's more often written as "a curate's egg ..", from a famous Punch cartoon.

So, overall, much more critical of the artists ("way behind the Impressionists and their successors") and therefore definitely at odds with my opinion. The potshots at Scotland and Glasgow are unwelcome as well ... being half-Scottish.
