Tiny: The Life of Erin Blackwell

Erin Blackwell comes through as a life giver. It's easy to judge her, a lot less easy to take the measure of her spirit and existence.

The combination of "Streetwise" and "Tiny" belongs on a short list with "Boyhood," the "Up" documentaries and "Hoop Dreams" as exemplars of time-capsule filmmaking.

Bell proves uncannily adept at capturing moments that seem to encapsulate a subject's entire emotional temperature.

The new documentary offers an interesting but sadly unsurprising update for Erin.
