Shirley Dent is too quick: she's appalled at the idea of a musical about Anne Frank. It's a concept she finds 'so mesmerisingly dreadful' that she needs Paul Celan's poetry to blot it out. She should have waited till she'd seen the musical or at least read a few reviews of it. I've argued this before so I'll keep it short here, but there is no forbidden medium for dealing with a Holocaust-related subject or theme. Dangers there most certainly are. You can try to make a Holocaust comedy and end up delivering Life Is Beautiful. But in principle a musical about Anne Frank is no more unthinkable than an opera on any serious subject, or than a cartoon treatment of surviving Auschwitz - like this one, which I recommend to anyone who hasn't read it. Dent ends by saying:
I do not think that the Holocaust is off-limits to the arts - only that it's best left to great artists...The flaw there is that you don't know who will do something well till they've done it; and though the great artists are few, it's one of the endearing features of our species that many people would like to have a shot at it.
