This inbetween the season 5 and 6 movie, is at all the effects part of the mithology of x-files, for this reason is totally faithful to the series. This is both a plus and a minus in my opinion. A plus, because all the people who follow the serie and watch the movies, recognize it immediately, and appreciate it for what it is: a very long cinematic episode of the x-files world (much before the Marvel try to do something similar with the different phases of its movies and tv series). The minus is that, if someone did not go to watch the movie to the cinema when it went out, would have surely lost too much in respect to the tv series. In fact, while in the preceding 5 seasons something rarely happens that give to the story a great advance, in the 2 hours of the movie a lot happens in a very short time. This is a bit unfair for the tv series itself, although as already said the movie should be just considered their extensions. The only real minus though, is that this movie is terribly long to be truly enjoyable, because the structure is the same of a tv episode, only 1h 20 minutes longer!
