If “The Cove” and “Blackfish” taught us anything, it’s that documentaries don’t necessarily require facts and figures to support a subject matter. Excessive emotionality will do just fine. “Dinosaur 13” absolutely convinces with its parade of injustice, exploring the wild story of Sue, the most complete Tyrannosaurus rex fossil ever discovered. It’s not a simple tale of ambitious paleontology and specimen recovery, but one of legal entanglements, betrayals, and media manipulation, spread out over the course of eight long, painful years. Cold details surrounding the fight over Sue aren’t enough for writer/director Todd Douglas Miller, who brings in syrupy indignation to fuel “Dinosaur 13,” diluting the picture’s power as a chilling reminder of powermad government types and the persistent corruption that infests the U.S. legal system.
