The midpoint of what would be a nine-season show, the fifth season of The X-Files (the first to be put on DVD in anamorphic widescreen format) gives fans a heavy heaping of what they love. For the mythology buffs, riveting episodes from the season bookends "Redux" and "The End" to several episodes in between tease with new revelations about the vast government conspiracies and alien invasion plot lines sketched in earlier seasons. But enough questions are left unanswered for the theatrical X-Files movie, which was released the subsequent summer, and the seasons that followed. Supporting characters like the Lone Gunmen, Agent Krycek, the Pusher Robert Modell, and Fox's father and sister Bill and Samantha Mulder are flushed out in more detail in several episodes that occasionally jump back in time to cover the prehistory of the X-files. New chess pieces are introduced, each raising new questions: the clairvoyant child Gibson Praise, Agent Spender, faceless alien resistance fighters with pyromaniacal tendencies, a child who may be Scully's, and Mulder's old flame, agent Diana Fowley (Mimi Rogers). All the time, no one knows who will be assassinated next, who is or isn't dead, just who isn't potentially a child of the Cigarette Smoking Man, and why the base of the neck is everyone's vulnerable spot. The creature feature stand-alone episodes vary in quality, but all are redeemed by the outrageously funny self-parody episode "Bad Blood," a fan favorite that guest stars Luke Wilson as a small-town sheriff who catches Scully's eye  (12**)
