On this edition of the Cinema Clash, Charlie and Hannah shed light on: THE DARK TOWER, a so-so battle of good vs. evil adapted from the Stephen King series; BRIGSBY BEAR, a quirky dramatic comedy with a surprising amount of heart; AN INCONVENIENT SEQUEL: TRUTH TO POWER, an engaging follow-up to Al Gore’s auspicious PowerPoint documentary on climate change; STEP, a feel-good doc about a step team at an all-girls school in inner-city Baltimore; and ESCAPES, an extremely odd documentary about actor-writer Hampton Fancher.
