There's little riper for a heartstring-plucking documentary than the life of a beloved star cut tragically short. In British filmmaker Nick Broomfield's Whitney 'Can I Be Me', he paints a poignant picture but struggles to get to the heart of his subject.

This is ironic, as the title of the film is a reference to Whitney Houston's own assertion that she commits a lot of time to being what other people want her to be: "Can I be me, now?" At one point, an interviewer asks how she wants to be remembered. In her typically disarming style - a deft marriage of thoughtful authenticity and practised evasion - Houston retorts that it surely doesn't matter as people will just remember her as they want to. It's an insightful moment into her personality but also acts as a pointed critique of a film attempting to piece together a portrait from the suppositions and recollections of a variety of friends and colleagues.
