Trek Nation is a relatively straight forward documentary with a clear premise. It follows Eugene Roddenberry’s search to find out more about his father Gene and to understand the cultural phenomenon of Star Trek. Directed by Scott Colthorp the film endeavours to explore the enduring appeal of the franchise as Eugene discovers more about the father he didn't know and the show that passed him by. Through interviews with cast and crew members from all five Star Trek shows, as well as fans and celebrities who were influenced by the show while growing up, Trek Nation methodically follows a linear path. Yet this uncomplicated approach proves to very effective and surprising candid.
