Trek Nation (2011)

A documentary that follows Gene Roddenberry's son (also called Gene) as he attempts to understand why Star Trek has had such a dramatic impact on the lives of so many people across the world.
Obviously. you'll need at least some interest in Trek to get the most from it, but what makes it special beyond that is the honesty that Gene Jr brings to the table. His goal is also to understand who his father was before he died, which is something he admits he was unable to achieve when Gene Sr was still alive. It's a sometimes painful journey for the son, but he doesn't shy away when the camera gets near, for which he should be wholeheartedly applauded.
