As recently noted, I just read a book on Anne Frank, whose birthday is today. Some have complained that the play The Diary Of Anne Frank prettifies and deracinates her story.
It's true the Pulitzer Prize-winning hit by the Hollywood husband and wife team of Frances Goodrich and Albert Hackett softened the original story, but is this a bad thing? The true tale is much more horrible, but it's still there, not only in the diary, but in many books that tell the wider history of how such a thing happened.
Art can help us face tough things, sometimes by providing the buffer of fiction, that spoonful of suger that makes us deal with something otherwise unbearable. But is this the right thing to do when we're talking about real-life tragedy? Or does it cheapen the memory of what happened? I don't know. But I'm guessing, as watered down as the Anne Frank play is, that it's introduced more people to her story than a stronger version that would have been harder to swallow.
PS Considering the somber subject, perhaps I shouldn't bring this up. Still, I can't help but think of the (apocryphal) story of when Pia Zadora starred in a production of The Diary Of Anne Frank. Allegedly she was so awful, when the Nazis were searching the house downstairs, someone in the audience shouted "She's in the attic!"
