'Batkid' harnesses the power of a documentary
May 7, 2015 5:30 AM - "Batkid Begins" arms us with a powerful weapon we can use to alter our world for good. That weapon is a four-letter word: hope. Not some abstract, nebulous, rhetorical concept, but a physical, empirical, tangible thing we can touch, see and hear. To witness how a little boy's dream -- to become a superhero so he can help others -- inspires people around the world to rally gives us that hope.
