The "politically correct"(PC) left is often no better than the Christian right when it comes to looking for ways to be offended by movies. The latest victim of PC backlash is "Nina," the film based on legendary jazz and blues singer and civil-rights icon Nina Simone. Nina is played by Zoe Saldana ("Avatar"), an actress "of color," as they say, but who required some skin darkening from the makeup department to portray the ebony Simone. This led to charges of "blackface" racism that sunk the film at the box office, yet it's hardly a caricature. Surely Saldana would also have been damned if she hadn't used make-up, accused of "whitening" a black artist.
