Thus ends the era in which I had yet to see all nine seasons of The X-Files plus two feature films. This last movie was released a few years after the series had already ended. At the end of the series, Dana Scully and Fox Mulder left the FBI and fled the UNited States, because they knew too much. An impeding Alien invasion was alluded too, indicating that it would never truly be blue skies for our star-crossed investigators.
X-Files had two basic episode structures. There were episodes that propelled the mythic arc and related to a conspiracy to cover up an colonization program and the creation of human-alien hybrids. There were also monster-of-the-week episodes, in which Mulder and Scully had to discover and defeat some sort of paranormal menace within the confines of a single episode. This movie could only be said to conform to the latter model, and it wasn't particularly interesting at that.
