According to this press release (the original here), and this breathless website, there will be ballet in the museum this summer. Ugh.
Why can't they just leave well enough alone? If something is significant enough to be shown in a museum, why can't they just show it? Why do they now need to add extra stuff? If the painting sucks, now amount of ballet (or music, or theater) is going to make it good. On the other hand if the painting is good, then the ballet (or music, or theater) is just going to take away from it by causing people not to be able to focus their full attention on it.
