The greatest love of all

Whitney Houston’s death did not resonate in pop culture with the same force that the losses of Prince and Michael Jackson did, but the documentary “Whitney. ‘Can I Be Me’ ” proves the singer’s demise was just as much of a tragedy. Directors Nick Broomfield and Rudi Dolezal strike an ideal balance between showing off the pop singer’s gifts and her shortcomings, despite minimal participation from those closest to her.

Candle in the wind

It’s nearly impossible to channel-surf these days without running into a Princess Diana special, most focusing on her death. “Diana and the Paparazzi” is no exception as filmmakers track the royal’s love-hate relationship with the press, laying much of the blame on her passing on the rabid photo takers and not the intoxicated chauffeur. The lopsided documentary is followed by “Diana: The Day We Said Goodbye,” narrated by Kate Winslet.
